Question

If 3x−y=12, what is the value of
8x
2y
?

Answer 1

If 3x-y=12, what is the value of 8x/2y?

Answer:

`(8x)/(2y) =(4x)/(3x-12)`

Explanation:

`3x-y=12`

`-y=12-3x`

`y=3x-12`-------------------------(equation 1)

Now,

`(8x)/(2y) =(8x)/(2(3x-12))`---------(from equation 1)

`=(8x)/(6x-24)`

`=(8x)/(2(3x-12))`

`=(4x)/(3x-12)`

Therefore, the value of
`(8x)/(2y) =(4x)/(3x-12)`
