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