9 - 4*x = 3*x - 40
94x=3x409 - 4 x = 3 x - 40
Detail solution
Given the linear equation:
9-4*x = 3*x-40

Move free summands (without x)
from left part to right part, we given:
4x=3x49- 4 x = 3 x - 49
Move the summands with the unknown x
from the right part to the left part:
(7)x=49\left(-7\right) x = -49
Divide both parts of the equation by -7
x = -49 / (-7)

We get the answer: x = 7
