4x + 12 = 8 – x Do this and i will be thankful :)

x = -4/5

Step-by-step explanation:

4x + 12 = 8 – x

4x + 4 = -x

4 = -5x

x = 4 / -5

x = -4/5

  x = 5

Step-by-step explanation:

Rearrange:

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

                    4*x-12-(8)=0

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  4x - 20  =   4 • (x - 5)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x-5 = 0

Add  5  to both sides of the equation :

                     x = 5
