Answer: Your answer is c

Step-by-step explanation: The first thing you can do is add the two equations together to cancel out x

5x-2y=3

-5x+4y=9

added them together will get us 2y=12, from here divide 2 and get y=6

Plug 6 into the first equation and solve for x.

5x-2(6)=3

5x-12=3, add 13 to the other side

5x=15, divide 5 and get the answer

x=3
