Give your answer as an improper fraction in its simplest form

Answer 1

`-(5)/(7)`

Explanation:

if we evaute the expression it will look like:

-6×7y=30

if we solve it :

(1) Simplify −6×7y to -42y

-42y=30

(2) Divide both sides by -42

y=
`-(30)/(42)`

(3) Simplify
`-(30)/(42) \\`

​
`-(5)/(7)`
