12\left(3-a\right)<0
Add 3 and 9 to get 12.
36-12a<0
Use the distributive property to multiply 12 by 3-a.
-12a<-36
Subtract 36 from both sides. Anything subtracted from zero gives its negation.
a>\frac{-36}{-12}
Divide both sides by -12. Since -12 is negative, the inequality direction is changed.
a>3
Divide -36 by -12 to get 3.
