The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$4 x = -8$$
Divide both parts of the equation by 4
We get the answer: x = -2
4*(x+5) = 12
Expand brackets in the left part
4*x+4*5 = 12
Move free summands (without x)
from left part to right part, we given:
$$4 x = -8$$
Divide both parts of the equation by 4
x = -8 / (4)
We get the answer: x = -2
