2w=-2.16+12.36
Add 12.36 to both sides.
2w=10.2
Add -2.16 and 12.36 to get 10.2.
w=\frac{10.2}{2}
Divide both sides by 2.
w=\frac{102}{20}
Expand \frac{10.2}{2} by multiplying both numerator and the denominator by 10.
w=\frac{51}{10}
Reduce the fraction \frac{102}{20} to lowest terms by extracting and canceling out 2.
