-9=-x+5x+8
Add -10 and 18 to get 8.
-x+5x+8=-9
Swap sides so that all variable terms are on the left hand side.
-x+5x=-9-8
Subtract 8 from both sides.
-x+5x=-17
Subtract 8 from -9 to get -17.
4x=-17
Combine -x and 5x to get 4x.
x=\frac{-17}{4}
Divide both sides by 4.
x=-\frac{17}{4}
Fraction \frac{-17}{4} can be rewritten as -\frac{17}{4} by extracting the negative sign.
