The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$10 x = 22$$
Divide both parts of the equation by 10
We get the answer: x = 11/5
10*x-15 = 7
Move free summands (without x)
from left part to right part, we given:
$$10 x = 22$$
Divide both parts of the equation by 10
x = 22 / (10)
We get the answer: x = 11/5
