Question

x + y = 3k
x - y = k

The solution of the system shown is _____.

Answer 1

x would equal 4k, because the y's cancel out

Answer 2

and y would have to equal -k

y=-k

Answer 3

so overal the solution to me would be (x,y) =(4k,-k); where k= whatever you want to place.

Answer 4

but if this is a algebra 2 question you would have to move the k to the other side making both equations = to 0
