O y = 2x - 30
O y=x+2
O y = x +7
O y=x-7

y = x - 7

Step-by-step explanation:

You take each equation and sub in for x and y.

The first equation would look like this:

16 = 2(23) - 30  Then you answer looks like this:

16 = 16 but if you did that for the second set in the column it looks like this:

18 = 2(25) - 30

18 = 50 - 30

18 = 20 which does not equal canceling the first answer.

And the second answer doesn't make sense because if x > y you shouldn't add to x. The same goes for the third answer.

So that leaves only one answer y = x - 7

Hope this helps

Sorry if this answer is long
