The solution

You have entered [src]
-x = 4 - 3*(3*x - 8)
$$- x = 4 - 3 \left(3 x - 8\right)$$
Detail solution
Given the linear equation:
-x = 4-3*(3*x-8)

Expand brackets in the right part
-x = 4-3*3*x+3*8

Looking for similar summands in the right part:
-x = 28 - 9*x

Move the summands with the unknown x
from the right part to the left part:
$$8 x = 28$$
Divide both parts of the equation by 8
x = 28 / (8)

We get the answer: x = 7/2
