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:
$$5 x = -53$$
Divide both parts of the equation by 5
We get the answer: x = -53/5
5*(x+9) = -8
Expand brackets in the left part
5*x+5*9 = -8
Move free summands (without x)
from left part to right part, we given:
$$5 x = -53$$
Divide both parts of the equation by 5
x = -53 / (5)
We get the answer: x = -53/5
