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:
$$- x = 3$$
Divide both parts of the equation by -1
We get the answer: x = -3
2*x-3*(x-3) = 12
Expand brackets in the left part
2*x-3*x+3*3 = 12
Looking for similar summands in the left part:
9 - x = 12
Move free summands (without x)
from left part to right part, we given:
$$- x = 3$$
Divide both parts of the equation by -1
x = 3 / (-1)
We get the answer: x = -3
