The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 4$$
Divide both parts of the equation by -2
We get the answer: x = -2
x+(8-3*x) = 12
Expand brackets in the left part
x+8-3*x = 12
Looking for similar summands in the left part:
8 - 2*x = 12
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 4$$
Divide both parts of the equation by -2
x = 4 / (-2)
We get the answer: x = -2
