Lets start by just leaving k in there and trying to combine the two equations to solve. Can you see an easy way to combine the 2 equations into 1?

i multiple , but i'd say k=10/-2=-5 so the answer i come up with is B

right so (i think) the easiest way is to add 2 times the first equation to the second equation: 2*4x-2*3y+(-8x+6y)=2*k+10 left hand side goes to zero, 2k+10=0 k=-5 you're absolutely right!
