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:
Divide both parts of the equation by -1
We get the answer: x = -4
2*x-3*(x+3) = -5
Expand brackets in the left part
2*x-3*x-3*3 = -5
Looking for similar summands in the left part:
-9 - x = -5
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by -1
x = 4 / (-1)
We get the answer: x = -4
