Question

-4 (5y + 5) = -120 y =

Answer 1

-4 (5y + 5) = -120

multiply the bracket by -4

(-4)(5y)=-20y

(-4)(5)=-20

-20y-20=-120

move -20 to +20

-20y-20+20=-120+20

-20y=-120+20

-20y=-100

divide both sides by -20 to get y by itself

-20y/-20=-100/-20

Answer: y=5

Answer 2

Answer:

Step-by-step explanation:

-4(5y + 5) = -120  

-4*5 y = -20 y

-4*5 = 20

-20 y + 20 = -120

         -20      -20

______________

-20 y             -100

-20 y               -20

y=50
