The solution

You have entered [src]
9*(x - 5) = -x
$$9 \left(x - 5\right) = - x$$
Detail solution
Given the linear equation:
9*(x-5) = -x

Expand brackets in the left part
9*x-9*5 = -x

Move free summands (without x)
from left part to right part, we given:
$$9 x = 45 - x$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = 45$$
Divide both parts of the equation by 10
x = 45 / (10)

We get the answer: x = 9/2
