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:
$$2 x = 3 x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 9$$
Divide both parts of the equation by -1
We get the answer: x = -9
2*(x-1)-5 = 3*x+2
Expand brackets in the left part
2*x-2*1-5 = 3*x+2
Looking for similar summands in the left part:
-7 + 2*x = 3*x+2
Move free summands (without x)
from left part to right part, we given:
$$2 x = 3 x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 9$$
Divide both parts of the equation by -1
x = 9 / (-1)
We get the answer: x = -9
