Question

Nine times a number y subtracted from 85 is seven times the sum of 4 and y

Answer 1

Answer: y = 3.5625

Explanation:

85 - 9y = 7(4 + y)

85 - 9y = 28 + 7y

-7y -7y

85 - 16y = 28

-85 -85

-16y = -57

`(-16y)/(-16)` =
`(-57)/(-16)`

y = 3.5625

(Check Work)

85 - (9 × 3.5625) = 7(4 + 3.5625)

85 - 32.0625 = 7 × 7.5625

52.9375 = 52.9375

Kind of a weird answer but... it checks out. Hope this helps!
