Question

15x+10y=8xy+28x find an expression for y in terms of x

Answer 1

y = 13x/10-8x

Explanation:

15x + 10y = 8xy + 28x

10y = 8xy + 13x

10y - 8xy = 13x

y(10 - 8x) = 13x

y = 13x/10-8x

Answer 2

y =
`(13x)/(10-8x)`

Explanation:

15x + 10y = 8xy + 28x ( subtract 15x from both sides )

10y = 8xy + 13x ( subtract 8xy from both sides )

10y - 8xy = 13x ← factor out y from each term on the left side

y(10 - 8x) = 13x ← divide both sides by (10 - 8x)

y =
`(13x)/(10-8x)`
