The solution

You have entered [src] 
9 - 2*(-4*x + 7) = 7
9−2(7−4x)=79 - 2 \left(7 - 4 x\right) = 7
Simplify
Detail solution
Given the linear equation:
9-2*(-4*x+7) = 7

Expand brackets in the left part
92*4*x-2*7 = 7

Move free summands (without x)
from left part to right part, we given:
8x=128 x = 12
Divide both parts of the equation by 8
x = 12 / (8)

We get the answer: x = 3/2
