3\left(3y+2\right)-4\left(y-6\right)>0
Multiply both sides of the equation by 12, the least common multiple of 4,3. Since 12 is positive, the inequality direction remains the same.
9y+6-4\left(y-6\right)>0
Use the distributive property to multiply 3 by 3y+2.
9y+6-4y+24>0
Use the distributive property to multiply -4 by y-6.
5y+6+24>0
Combine 9y and -4y to get 5y.
5y+30>0
Add 6 and 24 to get 30.
5y>-30
Subtract 30 from both sides. Anything subtracted from zero gives its negation.
y>\frac{-30}{5}
Divide both sides by 5. Since 5 is positive, the inequality direction remains the same.
y>-6
Divide -30 by 5 to get -6.
