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:
$$15 x = -105$$
Divide both parts of the equation by 15
We get the answer: x = -7
15*(x+10) = 45
Expand brackets in the left part
15*x+15*10 = 45
Move free summands (without x)
from left part to right part, we given:
$$15 x = -105$$
Divide both parts of the equation by 15
x = -105 / (15)
We get the answer: x = -7
