Answer:

x = 4

Explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-5*x+15-(35-10*x)=0

Pull out like factors :

5x - 20 = 5 • (x - 4)

_________________________________________

Solve : 5 = 0

This equation has no solution.

A a non-zero constant never equals zero.

_________________________________________

Solve : x-4 = 0

Add 4 to both sides of the equation :

x = 4

Hey!

-------------------------------------------------

Solution:

-5x + 15 = 35 - 10x

~Subtract 15 to both sides

-5x + 15 - 15 = 35 - 10x - 15

~Simplify

-5x = 20 - 10x

~Add 10x to both sides

-5x + 10x = 20 - 10x + 10x

~Simplify

5x = 20

~Divide 5 to both sides

5x/5 = 20/5

~Simplify

x = 4

-------------------------------------------------

Answer:

x = 4
