1.5=2b+30
Combine b and b to get 2b.
2b+30=1.5
Swap sides so that all variable terms are on the left hand side.
2b=1.5-30
Subtract 30 from both sides.
2b=-28.5
Subtract 30 from 1.5 to get -28.5.
b=\frac{-28.5}{2}
Divide both sides by 2.
b=\frac{-285}{20}
Expand \frac{-28.5}{2} by multiplying both numerator and the denominator by 10.
b=-\frac{57}{4}
Reduce the fraction \frac{-285}{20} to lowest terms by extracting and canceling out 5.
