Question

Im really confused bc ive tried everything and i cant figure this out

-3 7/10 = -3/-4y
its a rational equation

Answer 1

y = -
`(15)/(74)`

Explanation:

Given

- 3
`(7)/(10)` =
`(-3)/(-4)` y =
`(3)/(4)` y ( change the mixed number to an improper fraction )

-
`(37)/(10)` =
`(3)/(4)` y

Multiply through by 20 ( the LCM of 10 and 4 )

- 74 = 15y ( divide both sides by 15 )

-
`(74)/(15)` = y
