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:
$$- 5 x = 20$$
Divide both parts of the equation by -5
We get the answer: x = -4
x-2*(3*x+2) = 16
Expand brackets in the left part
x-2*3*x-2*2 = 16
Looking for similar summands in the left part:
-4 - 5*x = 16
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = 20$$
Divide both parts of the equation by -5
x = 20 / (-5)
We get the answer: x = -4
