The solution

You have entered [src]
7*x - 8 + -4*x + 5 = 15
$$\left(5 - 4 x\right) + \left(7 x - 8\right) = 15$$
Detail solution
Given the linear equation:
(7*x-8)-(4*x-5) = 15

Expand brackets in the left part
7*x-8-4*x+5 = 15

Looking for similar summands in the left part:
-3 + 3*x = 15

Move free summands (without x)
from left part to right part, we given:
$$3 x = 18$$
Divide both parts of the equation by 3
x = 18 / (3)

We get the answer: x = 6
