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:
$$- 15 x = 45$$
Divide both parts of the equation by -15
We get the answer: x = -3
8-5*(8+3*x) = 13
Expand brackets in the left part
8-5*8-5*3*x = 13
Looking for similar summands in the left part:
-32 - 15*x = 13
Move free summands (without x)
from left part to right part, we given:
$$- 15 x = 45$$
Divide both parts of the equation by -15
x = 45 / (-15)
We get the answer: x = -3
