-2a+9<0
Combine a and -3a to get -2a.
-2a<-9
Subtract 9 from both sides. Anything subtracted from zero gives its negation.
a>\frac{-9}{-2}
Divide both sides by -2. Since -2 is negative, the inequality direction is changed.
a>\frac{9}{2}
Fraction \frac{-9}{-2} can be simplified to \frac{9}{2} by removing the negative sign from both the numerator and the denominator.
