multiply the first equation by -1 all the way across and add to the second one.

Answer 2

ok!

Answer 3

I got no solution

Answer 4

no you should get a solution. if you multiply the first one by -1 you get
\[-x+5y=43\] and the second one is
\[2x-5y=-41\] if you add the two you get
\[x=2\]

Answer 5

ok i now have A

Answer 6

no it is not A because you solved for x and x is the first coordinate, not the second one. it should be (2,9)
