The solution

You have entered [src]
4*x - 6 + -9*x + 4 = 18
$$\left(4 - 9 x\right) + \left(4 x - 6\right) = 18$$
Detail solution
Given the linear equation:
(4*x-6)-(9*x-4) = 18

Expand brackets in the left part
4*x-6-9*x+4 = 18

Looking for similar summands in the left part:
-2 - 5*x = 18

Move free summands (without x)
from left part to right part, we given:
$$- 5 x = 20$$
Divide both parts of the equation by -5
x = 20 / (-5)

We get the answer: x = -4
