Question

Consider this system of equations and the partial solution below.

6 x + 2 y = 6.
7 x + 3 y = 9.

Multiply the first equation by –3.
Multiply the second equation by 2.
Add the resulting system of equations.

Which terms will cancel when you add the resulting system of equations?

Answer 1

A

Explanation:

Answer 2

The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.
