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