The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 9
We get the answer: x = 50/9
(x-3)*9 = 23
Expand brackets in the left part
x*9-3*9 = 23
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 9
x = 50 / (9)
We get the answer: x = 50/9
