2w=9+21.5
Add 21.5 to both sides.
2w=30.5
Add 9 and 21.5 to get 30.5.
w=\frac{30.5}{2}
Divide both sides by 2.
w=\frac{305}{20}
Expand \frac{30.5}{2} by multiplying both numerator and the denominator by 10.
w=\frac{61}{4}
Reduce the fraction \frac{305}{20} to lowest terms by extracting and canceling out 5.
