Answer 2

y = -8

Explanation:

This problem is solved using substitution. So you need to start by substituting in the -9 for the 'x' in the main equation. This will give you something that looks like this:

`7(-9)-10y=17`

Now just solve!

`7(-9)-10y=17\\\\-63-10y=17\\\\-10y=80\\\\y=-8`

Hope this helps :)
