The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$9 x = 72$$
Divide both parts of the equation by 9
We get the answer: x = 8
9*x-2 = 70
Move free summands (without x)
from left part to right part, we given:
$$9 x = 72$$
Divide both parts of the equation by 9
x = 72 / (9)
We get the answer: x = 8
