x+4=9x-5-\left(-x\right)
To find the opposite of 5-x, find the opposite of each term.
x+4=9x-5+x
The opposite of -x is x.
x+4=10x-5
Combine 9x and x to get 10x.
x+4-10x=-5
Subtract 10x from both sides.
-9x+4=-5
Combine x and -10x to get -9x.
-9x=-5-4
Subtract 4 from both sides.
-9x=-9
Subtract 4 from -5 to get -9.
x=\frac{-9}{-9}
Divide both sides by -9.
x=1
Divide -9 by -9 to get 1.
