The solution

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

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

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

Move free summands (without x)
from left part to right part, we given:
$$- 9 x = - x - 28$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-8\right) x = -28$$
Divide both parts of the equation by -8
x = -28 / (-8)

We get the answer: x = 7/2
