What is 4^2y-3^2=-5y+(-5+7) explain step by step i need this asap : /

y = 11/21

To solve this first evaluate the power (then calculate the sum):

y - = 5y + (-5 + 7)

16y - 9 = -5y + 2

Next Move terms (move variable to the left side and change its sign) (Move constant to the right side and change its sign):

16y - 9 = -5y + 2

16y + 5y = 2 + 9

Next Collect the like terms and calculate the sum:

16y + 5y = 2 + 9

21y = 11

Lastly divide both sides of the equation by 21:

21y = 11

y =

simplify stuff by pemdas, 4^2=16, 3^2=9, -5+7=2

add 5y to both sides

add 9 both sides

divide both sides by 21

24

Step-by-step explanation:

120/24 = 5

168/24 = 7

5 and 7 do not have any common factors, hence they cannot be reducible.
