The solution

You have entered [src]
-9 - 4*x + 12 = 0
$$\left(- 4 x - 9\right) + 12 = 0$$
Detail solution
Given the linear equation:
-9-4*x+12 = 0

Looking for similar summands in the left part:
3 - 4*x = 0

Move free summands (without x)
from left part to right part, we given:
$$- 4 x = -3$$
Divide both parts of the equation by -4
x = -3 / (-4)

We get the answer: x = 3/4
