9 - 4*x + 5*x - 11 = 10
$$\left(5 x + \left(9 - 4 x\right)\right) - 11 = 10$$
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$x = 12$$
We get the answer: x = 12
9-4*x+5*x-11 = 10
Looking for similar summands in the left part:
-2 + x = 10
Move free summands (without x)
from left part to right part, we given:
$$x = 12$$
We get the answer: x = 12
