The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$2 x = 22$$
Divide both parts of the equation by 2
We get the answer: x = 11
2*x-7 = 15
Move free summands (without x)
from left part to right part, we given:
$$2 x = 22$$
Divide both parts of the equation by 2
x = 22 / (2)
We get the answer: x = 11
