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:
$$- 2 x = - x - 3$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = -3$$
Divide both parts of the equation by -1
We get the answer: x = 3
5-2*(x-1) = 4-x
Expand brackets in the left part
5-2*x+2*1 = 4-x
Looking for similar summands in the left part:
7 - 2*x = 4-x
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = - x - 3$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = -3$$
Divide both parts of the equation by -1
x = -3 / (-1)
We get the answer: x = 3
