$$\frac{5 \left(\frac{5 x}{6} - \frac{1}{2}\right)}{6} = \frac{5}{6}$$
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:
$$\frac{25 x}{36} = \frac{5}{4}$$
Divide both parts of the equation by 25/36
We get the answer: x = 9/5
(5/6*x-1/2)*5/6 = 5/6
Expand brackets in the left part
5/6*x*5/6-1/2*5/6 = 5/6
Move free summands (without x)
from left part to right part, we given:
$$\frac{25 x}{36} = \frac{5}{4}$$
Divide both parts of the equation by 25/36
x = 5/4 / (25/36)
We get the answer: x = 9/5
