The solution

You have entered [src]
-2*(6 + x) = 18 - 3*x
$$- 2 \left(x + 6\right) = 18 - 3 x$$
Detail solution
Given the linear equation:
-2*(6+x) = 18-3*x

Expand brackets in the left part
-2*6-2*x = 18-3*x

Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 30 - 3 x$$
Move the summands with the unknown x
from the right part to the left part:
$$x = 30$$
We get the answer: x = 30
