Answer:

y=6

Step-by-step explanation:

-6y+15=-21

-6y=-21-15 (it becomes negative on this side.)

-6y=-36 (divide both sides by -6.)

y=6

Answer:

your answer is 6

Step-by-step explanation:

Step 1: Subtract 15 from both sides

-6y + 15 = -21

        -15 = -15

Step 2: Divide both sides by -6

-6y=-36

-6= -6

y=6
