Mathematically x=24 is an equation, because from another point of view, this equation is x-24=0, and if you ask if this is an equation, those teachers will say yes. Whether a formula is an equation or not does not depend on the form it takes, but on whether there are unknowns in the formula. The process of solving an equation is actually the process of deforming the equation by identity until it reaches the simplest equation (e.g., x=24) where the result can be seen at a glance, and it can be said that the formula obtained at each step is an equation equivalent to the original equation.
Of course, there is no objection to those teachers treating x=24 as the solution of the equation, but this argument of separating the equation from the solution of the equation is meaningless, because the solution of the equation can also be said to be only 24, not x=24, why? That's because we see x as an unknown rather than a solution all along. From this point of view, it is more in line with the laws of mathematical thinking to think of x=24 as the simplest equation.
-
Yes. There is an unknown number x
It's the equation. In general, this is a matter of opinion. But it doesn't matter if it's an equation or not.
-
By definition, yes, yes, and to say no is to say that the definition is not tight! Who said that the solution of an equation is not an equation! There are so many opinions, why is there any need!
That definition is set by people, you say yes, change the definition is not, what's the use of arguing about it? Is it good to focus on scientific research?
-
The solution of the equation: The value of the unknown that equalizes the left and right sides of the equation is called the solution of the equation.
That is to say, he is an equation first before he can be a solution, and since he is a solution, he must be an equation.
There's no point in discussing this.
-
No; Because there are no unknowns in the equation (x already knows how much).
-
Yes, an equation is defined as: an equation with unknowns. Based on this, it can be determined that it is an equation.
-
Yes, by the definition of the equation, there are variables connected by constants and equal signs, yes!
-
is an equation, which by definition conforms to the definition of an equation, geometrically a straight line of x=24, but it is not a function, because a function must satisfy one or more x to uniquely determine a y, so it is an equation but not a function.
-
I'm also a puzzled question, and as some friends said, I don't think this x is among the unknowns. But it doesn't look like that's going to be in the exam questions, right?

The questions raised by the landlord can easily be dismissed as "meaningless" or even "boring". But I think it's a very serious issue: when learning mathematics, you should get to the bottom of it, and if the basic concepts are not clear, it will lead to confusion of concepts.
Let's review how to solve the equation first. The process of solving equations is "gradually reduced to simple equations until the simplest equations". This "simplest equation" is the solution of the original equation.
1) Since it is "gradually reduced to simple equations", all forms of any step, up to the final step, are equations.
2) In the process of solving the equation, due to the influence of the method, it is possible to produce root additions - there is the simplest form, but it does not conform to the original equation.
3) The definition of "solution" is relative to "root increase": the simplest equation of the composite original equation is defined as "the solution of the original equation".
To sum up, in terms of x=24 alone, there is no doubt that it is an equation.
However, if the answer is obtained in solving the equation (assuming that there is also x=-10 and does not conform to the original equation), then:
x=24 is the solution, while x=-10 is not.
But in terms of mathematical form, x=24 and x=-10 are both equations.
In elementary algebra, "equation" is an independent concept that depends only on its own form, while "solution" is not an independent concept, it depends on the original equation in addition to the form of the simplest equation.
It should be pointed out that when solving complex equations (such as calculus equations) in the future, the "solution" obtained is still a complex equation, even more complex than the original equation, and is not a constant at all.
-
Divide both sides of the equation by 2 at the same time, and you get x+4=12, and subtract 4 from both sides at the same time, and solve x=12-4=8.
-
24 divided by 2 equals equal to 8It's okay to reason backwards.
-
The first step is to remove the parentheses: 2x+2x4=24
The second step, 2x+8=24
In the third step, 2x=24-8=16
Step 4, x=16 2=8
So, the final answer is equal to 8.
-
You can first look at the left one as two multipliers, x+4 one, 2 one, and then use 24 2 to get the result of one of the multipliers. 12-4=8,x=8
-
Unblock this equation, and directly square both sides of the equation at the same time.
Solution: x = 24
x=±√24
x=±2√6
The solution of the original equation is x=2 and x=-2 6.

The method of arguing and fighting is as follows, carrying the grind.
Please do the divination test:
-
x = 24 to solve this equation, so that the banquet contains a direct hail auspicious method to open the source lead.
x = 24 solution: x = 2 6
x1=2√6,x2=-2√6
-
Knowing the quadratic equation x 24, solving the equation is to square the left and right sides of the equation at the same time, and we can get x 2 6.
-
The solution x is equivalent to finding the square root of 24, which is equal to plus or minus two times the root number six, that is, x is equal to the plus or minus double root number six.
-
Solution: x 2 = 24
x=±√24
x=±2√6
The rise of the original equation is solved by the rise of the original equation as x1=2 6, x2=-2 and sells 6
-
x^2=24
The open method x = 24 = 2 6, and the solution of the equation is x = 2 6,
-
It is understandable whose square is 24, and finding x is equivalent to finding the square root of 24, x 2 root number 6
-
Solution: x = 24
Zen touch x is the square root of 24, according to the square of the old root, x = 24
x=±2√6
