Given that 2x – 7y= 30 Find y when x = -3
Give your answer as an improper fraction in its simplest form.

y= -36/7

Explanation:

2x - 7y = 30

-6 - 7y = 30

-7y = 36

y = -36/7

-5.14

Explanation:

2(-3)-7y=30

-6-7y=30

-7y=36

divide both side by -7

-7y÷-7 36÷-7

so -7 cancel -7

the answer will be y=36÷-7
