How do you solve equations for X 1 5X 4?

x－1/5ⅹ＝4

x＝4÷4/5

x 5 hope it helps, thank you!

<> the calculation process, pay attention to the calculation of the score. Hope these are helpful to you, thanks.

The unary equation is solved, and the calculation process is as follows:

x-1/5x=4

4/5x=4x=5

The variant is x 4 + fifths x

From this, 4 is four-fifths of the value of x.

substitution, x yields 5

Merge similar items to obtain.

4/5x=4

Divide both sides by 4 5 at the same time

Get x=5

<> "There are two solutions to this equation.

The root number is opened on both sides first.

Get x 5 7

Then move the item, subtracting 5 from both sides at the same time

Get x 7 5

The solution is as shown in the figure above.

Hope mine is helpful to you.

(x+5)²=7

Solution: Open the square, got.

x+5=±√7

Solve this equation and get.

x1=x2=±√7-5.

Hello, use the collocation method to solve the equation, 7x 2-5x-1=0

x-5/14）^2=53/196

x=（5±√53）/14

Hello! Glad for your question!

Solution: 5x=7x -1

7x²-1－5x＝0

Finding the solution of an equation using the formula method: x (5 53) 14 Yours is the biggest support for me! Break a leg! Thank you!

7x²-5x-1=0

x=（5±√53）/14

Formula method solution or matching method solution.

Solution: Subtract 15 from both sides of the equation to get.

15-15+x=47-15

x=32

x+15+x=47

2x+15=47

2x=47-15

2x=32x=16

First of all, it is necessary to merge the same kind of items, and the spring talks about merging the items containing x into one branch.

Summary. x: (x-5) = 7 8: 6 7 How to solve the equation.

Hello, the key to solving this problem is the ratio, which can be seen as division, and then simplify the two sides of the formula, you can get the result.

How to solve the equation with 5x -7x-4=0.

Hello, dear <>

Here, according to the question you provided, how to solve the equation 5x -7x-4 = 0 for you to find the following: Solution:

1.The equation is reduced to the standard form of a quadratic equation: 5x -7x-4=0=> 5x -7x+3x-4=0=> 5x +3x-4=02

Find the product of the quadratic and primary coefficients: a b = 5 (-4) = 203Find the solution of a quadratic equation:

b -4ac = 7) -4 5 (-4)) 49+80 = 129x =b+ δ2a = 7) + 129) (2 5) = =b- δ2a = 7)- 129) (2 5) = Therefore, the solution of 5x -7x-4=0 is x =, x =
