The solution
Detail solution
Given the linear equation:
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-x-8 = 3
Looking for similar summands in the left part:
-8 + 2*x = 3
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
