Given that 2x - 9y = 22

Find y when x = 7

Give your answer as a fraction in its simplest form.

y=-8/9

Step-by-step explanation:

This is a substitution question, since we are given the value for x we are to look for y

And this can be done by making y the subject of formula

2x-9y=22

Let's make y the subject of formula

2x-22=9y

Let's substitute the value of x

2 (7) - 22=9y

14-22=9y

-8=9y

Divide both sides by 9

y=-8/9

Therefore the final answer for y is - 8/9
