1/3 ( 30y + 6 ) = 32
1/3 is a fraction. Solve for y
​

y=3

Step-by-step explanation:

30y+6/3=23

6(5y+1)/3=32

2(5y+1)=32

5y+1=32/2

32/2=16

5y=16-1

16-1=15

y=15/5

y=3

1 1/5

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
