8.7w-3-5.5w=3.4
Subtract 5.5w from both sides.
3.2w-3=3.4
Combine 8.7w and -5.5w to get 3.2w.
3.2w=3.4+3
Add 3 to both sides.
3.2w=6.4
Add 3.4 and 3 to get 6.4.
w=\frac{6.4}{3.2}
Divide both sides by 3.2.
w=\frac{64}{32}
Expand \frac{6.4}{3.2} by multiplying both numerator and the denominator by 10.
w=2
Divide 64 by 32 to get 2.
