Question

What is the solution of the system? Use elimination.

Answer 1

C
hope it helps.........

Answer 2

Okay, start by replacing each x and y variable with the coordinates.

3*3=9
4*4=16
9-16= -7.
A can be eliminated.

3*0=0
4*6=24.
0-24= -24

Now we test the second equation.
0+6 does not equal negative one.

3*-4= -12
4*3=12
-12-12= -24

Now we test the second one again.

-4+3= -1.
We did it, but let's check the last problem anyways.

Starting with the second equation, x + y = –1, we know 4-3=1, not -1. So we did it.
Your answer is C. :)
