Give your answer as an improper fraction in its simplest form

Answer 1

Answer:

$-\frac{5}{7}$

Step-by-step 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=$-\frac{30}{42}$

(3) Simplify $-\frac{30}{42}$

​ $-\frac{5}{7}$
