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
