Answer: x = -11/8 = -1.375

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 :

(x-4)-(x+7)-(8*x)=0

Step by step solution :

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

-11 - 8x = -1 • (8x + 11)

Equation at the end of step 1 :

Step 2 :

Solving a Single Variable Equation :

2.1 Solve : -8x-11 = 0

Add 11 to both sides of the equation :

-8x = 11

Multiply both sides of the equation by (-1) : 8x = -11

Divide both sides of the equation by 8:

x = -11/8 = -1.375

One solution was found :

x = -11/8 = -1.375
