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:
$$2 x = 11$$
Divide both parts of the equation by 2
We get the answer: x = 11/2
(3*x-2)-(x-1) = 10
Expand brackets in the left part
3*x-2-x+1 = 10
Looking for similar summands in the left part:
-1 + 2*x = 10
Move free summands (without x)
from left part to right part, we given:
$$2 x = 11$$
Divide both parts of the equation by 2
x = 11 / (2)
We get the answer: x = 11/2
