35-4b+12b=105
Multiply both sides of the equation by 3.
35+8b=105
Combine -4b and 12b to get 8b.
8b=105-35
Subtract 35 from both sides.
8b=70
Subtract 35 from 105 to get 70.
b=\frac{70}{8}
Divide both sides by 8.
b=\frac{35}{4}
Reduce the fraction \frac{70}{8} to lowest terms by extracting and canceling out 2.
