Question

Help Picture below ..........

Answer 1

A

Explanation:

Multiply them according to the problem.

`6x+2y=6 \\ \\ -3(6x+2y)=(6)*-3 \\ \\ -18x-6y=-18 \\ \\ \\ 7x+3y=9 \\ \\ 2(7x+3y)=(9)*2 \\ \\ 14x+6y=18`

As you can see, the only terms in the two equations that can cancel out are
`-6y` and
`6y`.
