Asap i need with these questions i have to show work too.

1: Simplify 15/20 to 3/4

y/4=3/4

Multiply both sides by 4

y=3/4×4

Simplify 3/4×4 to 12/4

y=12/4

Simplify 12/4 to 3

y=3

2: Multiply both sides by z-3

6=8/5(z-3)

Simplify 8/5(z-3) to 8(z-3)/5

8(z-3)/5

Multiply both sides by 5

6×5=8(z-3)

Simplify 6×5 to 30

30=8(z-3)

Divide both sides by 8

30/8=z-3

Simplify 30/8 to 15/4

15/4=z-3

Add 3 to both sides

15/4+3=z

Simplify 15/4+3 to 27/4

27/4=z Switch sides z=27/4

626

Step-by-step explanation:

hope this helps
