Answer: y = 1.4 (rounded)

Explanation:

y = 1.4 because if you turn the expression from R = 4x +8y and turn it into 32 = 4 x 4 + 8y. After that you times 4 x 4 which equals 16. Then if you add 16 + 8y which equals 24y. Then you lastly divide 32 by 24 which will give you 1.33333333 but rounded it equals 1.4.

If it's differently it's y = 2.
