Please I beg you help me

8(7-4y)=20
Solve for y

y=9/8

Step-by-step explanation:

dont have one

y=9/8

Step-by-step explanation:

8(7-4y)=20

8(7)-8(4y)=20

56-32y=20

-32y=-36

y=9/8 or 1.125

Hope This Helps :)

the first option is the answer.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
