Answer:
Your answer is infinitely many solutions
Step-by-step explanation:
To use elimination you have to get one of the variables to be the opposite of each other, so here you would do:
-2(2x+y = 7)
4x+2y= 14
You multiply the top by -2 to get the opposite of 2y, which is -2y. This in turn multiplies everything by -2 on the top solution giving us the top equation below.
-4x-2y = -14
+ 4x+2y = 14
--------------------
0 = 0
If you add those 2 solutions then you get 0 = 0, which is infinitely many solutions
