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:
$$2 x = 12$$
Divide both parts of the equation by 2
We get the answer: x = 6
5-2*(3-x) = 11
Expand brackets in the left part
5-2*3+2*x = 11
Looking for similar summands in the left part:
-1 + 2*x = 11
Move free summands (without x)
from left part to right part, we given:
$$2 x = 12$$
Divide both parts of the equation by 2
x = 12 / (2)
We get the answer: x = 6
