Answer: y=2x-23, x=8; (8, -7)

Step-by-step explanation:

First, arrange both equations in y=mx+b form and evaluate; y=2x-23 & x=8

Now, use x=8 to substitute the value into the y=2x-23 equation;

y=2(8)-23, this will give you a completed ordered pair;

(x=8, y=-7)

Hope this helps !

x+y=8+(-7)

=1
