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:
$$- x = 0$$
Divide both parts of the equation by -1
We get the answer: x = 0
-4*x+3*(x-1) = -3
Expand brackets in the left part
-4*x+3*x-3*1 = -3
Looking for similar summands in the left part:
-3 - x = -3
Move free summands (without x)
from left part to right part, we given:
$$- x = 0$$
Divide both parts of the equation by -1
x = 0 / (-1)
We get the answer: x = 0
