49.35b+54.1-41b=87.5
Subtract 41b from both sides.
8.35b+54.1=87.5
Combine 49.35b and -41b to get 8.35b.
8.35b=87.5-54.1
Subtract 54.1 from both sides.
8.35b=33.4
Subtract 54.1 from 87.5 to get 33.4.
b=\frac{33.4}{8.35}
Divide both sides by 8.35.
b=\frac{3340}{835}
Expand \frac{33.4}{8.35} by multiplying both numerator and the denominator by 100.
b=4
Divide 3340 by 835 to get 4.
