(8th grade math) how do i do this???

y = 5, y = -5

Step-by-step explanation:

In this question, you would have to solve the equation for "y".

Solve:

-3y² = -75

Divide both sides by -3.

y² = 25

Square root both sides to cancel out the exponent.

√y² = √25

y = ±√25

Simplify the square root for both positive and negative terms.

y = 5

y = -5

Your final answer would be y = 5 and y = -5

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
