Solve the following system and show all of your work.
x − 2y = 14
x + 3y = 9

Answer 1

subtract one equal from the other and that gets rid of the x term.

Answer 2

equation*

Answer 3

-5y=5

implies that y=-1

plug in y=-1 to either equation (you can do this because the solution for y needs to satisfy both equations).

then solve for x.
