The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$3 x = 2 x - 2$$
Move the summands with the unknown x
from the right part to the left part:
$$x = -2$$
We get the answer: x = -2
3*(x+2) = 2*(x+2)
Expand brackets in the left part
3*x+3*2 = 2*(x+2)
Expand brackets in the right part
3*x+3*2 = 2*x+2*2
Move free summands (without x)
from left part to right part, we given:
$$3 x = 2 x - 2$$
Move the summands with the unknown x
from the right part to the left part:
$$x = -2$$
We get the answer: x = -2
