Which of these is the solution to the system of equations?

Y=12x-18

Y=13x-18

Is it a. (-18,0)

B. (0,-18)

C. (1,-6)

D. (1,-5)

The best way to solve is by elimination.

First, write the equations in standard form.

12x-y=18

13x-y=18

Multiple the bottom equation by - 1

12x-y=18

-13x+y=-18

Add.

-x=0

x=0 Plug into other equation

12 (0) - y=18

0-y=18

-y=18

y=-18

Your answer is B. (0,-18)
