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