The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right 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 -1
We get the answer: x = -14
3*x-5*(2*x+1) = 3*(3-2*x)
Expand brackets in the left part
3*x-5*2*x-5*1 = 3*(3-2*x)
Expand brackets in the right part
3*x-5*2*x-5*1 = 3*3-3*2*x
Looking for similar summands in the left part:
-5 - 7*x = 3*3-3*2*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 -1
x = 14 / (-1)
We get the answer: x = -14
