Best ResponseYou've already chosen the best response.0Lets 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?

Best ResponseYou've already chosen the best response.1i multiple , but i'd say k=10/2=5 so the answer i come up with is B

Best ResponseYou've already chosen the best response.0right so (i think) the easiest way is to add 2 times the first equation to the second equation: 2*4x2*3y+(8x+6y)=2*k+10 left hand side goes to zero, 2k+10=0 k=5 you're absolutely right!
