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:
$$- 4 x = -4$$
Divide both parts of the equation by -4
We get the answer: x = 1
2*x-2*(3*x+4) = -12
Expand brackets in the left part
2*x-2*3*x-2*4 = -12
Looking for similar summands in the left part:
-8 - 4*x = -12
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = -4$$
Divide both parts of the equation by -4
x = -4 / (-4)
We get the answer: x = 1
