The solution

You have entered [src]
12 + 3*(x - 1) = 0
$$3 \left(x - 1\right) + 12 = 0$$
Detail solution
Given the linear equation:
12+3*(x-1) = 0

Expand brackets in the left part
12+3*x-3*1 = 0

Looking for similar summands in the left part:
9 + 3*x = 0

Move free summands (without x)
from left part to right part, we given:
$$3 x = -9$$
Divide both parts of the equation by 3
x = -9 / (3)

We get the answer: x = -3
