2*x + 9*x - 5 = 0

$$\left(2 x + 9 x\right) - 5 = 0$$

Simplify

Detail solution

Given the linear equation:

2*x+9*x-5 = 0

Looking for similar summands in the left part:

-5 + 11*x = 0

Move free summands (without x)
from left part to right part, we given:
$$11 x = 5$$
Divide both parts of the equation by 11

x = 5 / (11)

We get the answer: x = 5/11
