Math:

Step #1: Simplify both sides of the inequality.
30>5z−15

Step #2: Flip the equation.

5z−15<30

Step #3: Add 15 to both sides.
5z−15+15<30+15

5z<45

Step #4: Divide both sides by 5.

5z/5=45

Your Answer:
z<9

Distribute the negative to get 30>-5z-15+10z

Combine like terms to get 30>5z-15+

Add 15 to each side to get 45>5z

Divide by 5 on each side to get that 9>z

Your answer will be 9>z
