9-7w-8w=8
Subtract 8w from both sides.
9-15w=8
Combine -7w and -8w to get -15w.
-15w=8-9
Subtract 9 from both sides.
-15w=-1
Subtract 9 from 8 to get -1.
w=\frac{-1}{-15}
Divide both sides by -15.
w=\frac{1}{15}
Fraction \frac{-1}{-15} can be simplified to \frac{1}{15} by removing the negative sign from both the numerator and the denominator.
