-2.1b<4.4-7.2
Subtract 7.2 from both sides.
-2.1b<-2.8
Subtract 7.2 from 4.4 to get -2.8.
b>\frac{-2.8}{-2.1}
Divide both sides by -2.1. Since -2.1 is negative, the inequality direction is changed.
b>\frac{-28}{-21}
Expand \frac{-2.8}{-2.1} by multiplying both numerator and the denominator by 10.
b>\frac{4}{3}
Reduce the fraction \frac{-28}{-21} to lowest terms by extracting and canceling out -7.
