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