The solution

You have entered [src]
5*x         
--- - 15 = x
 2          
$$\frac{5 x}{2} - 15 = x$$
Detail solution
Given the linear equation:
(5/2)*x-15 = x

Expand brackets in the left part
5/2x-15 = x

Move free summands (without x)
from left part to right part, we given:
$$\frac{5 x}{2} = x + 15$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{3 x}{2} = 15$$
Divide both parts of the equation by 3/2
x = 15 / (3/2)

We get the answer: x = 10
