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 1/8
We get the answer: x = 27
(x-19)/8 = 1
Expand brackets in the left part
x/8-19/8 = 1
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 1/8
x = 27/8 / (1/8)
We get the answer: x = 27
