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:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by -4
We get the answer: x = -27/4
-15-3*(x-2) = 18+x
Expand brackets in the left part
-15-3*x+3*2 = 18+x
Looking for similar summands in the left part:
-9 - 3*x = 18+x
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by -4
x = 27 / (-4)
We get the answer: x = -27/4
