What is the basis for solving the equation x plus eight equals 16 equals the first step x equals 16

x+8=16

x+8-8=16-8

The basis for the first step x equal to 16-8 is:

Property 1 of the equation, i.e., adding (or subtracting) the same integer to both sides of the equation at the same time, the equation still holds. ）

Definition of Equation:

Equations that contain an equal sign are called equations (a mathematical term).

Form: Concatenate two equal numbers (or numbers represented by letters) with "=".

Basic properties of the equation:

Property 1 adds (or subtracts) the same integer to both sides of equation at the same time, and the equation still holds.

If a=b, then a+c=b+c

The equation still holds if both sides of the property 2 equation are multiplied or divided by the same non-0 whole at the same time.

If a=b, then there is a·c=b·c

or a c = b c (c≠0).

The property 3 equation is transitive.

If a1 = a2, a2 = a3, a3 = a4 ,......an=an, then a1=a2=a3=a4=......=an

Extension: Extension 1: Both sides of the equation are subtracted by a number or formula at the same time, and the result is still equal.

If a=b, then c-a=c-b

Extension 2: Take opposite numbers on both sides of the equation and the result is still equal.

If a=b, then -a=-b

Extension 3: When both sides of the equation are not equal to 0, the result is still equal when the same number or formula is divided.

If a=b≠0, then c a=c b

Extension 4: When the two sides of the equation are not equal to 0, the reciprocal of the two sides is taken and the results are still equal.

If a=b≠0, then 1 a=1 b

x+8=16

The equation for numbers that add or subtract the same on both sides of the equation at the same time does not change:

Subtract 8 from both sides of the equation at the same time: x+8-8=16-8x=8

Solve the equation:6x-18=x+18

6x-x=18+18

5x=36x=36/5

x=test: left=right=

Significance of solving equations:There are five steps to solve a one-dimensional equation, i.e., denominating, deparentheses, shifting terms, merging similar terms, and coefficients to 1, all of which are performed according to the properties of integers and equations.

The unary equation can solve most of the engineering problems, travel problems, distribution problems, profit and loss problems, integral table problems, billing problems, and number problems. If you use only arithmetic, some problems can be incredibly complex and difficult to understand.

Solution: Solve the equation, the solution of this equation is x = 2

Seven x plus eight minus five x and other boys are suspected in the twelve.

7x + 8 - 5x = 12

2x + 8 = 12

2x = 12 - 8

2x = 4

x = 4 ÷ 2

x = 4 × 1/2

x = 4/2

x = 2 Answer: The solution of this equation is x = 2

Summary. 8=16/x

8x=16x=16÷8

x=2 eight is equal to 16/x, how to solve, find the process.

8=16/x8x=16x=16÷8x=2

Pro, shift the term to get x=2 [than the heart].
