I just finished this test and the answer is "Multiply the second equation by −4 to get −16x − 4y = −80" So it was A for me

<span>A) 2x + 4y = 14
B) 4x + y = 20
If you multiply equation A by -2, then when the equations are added, the x will be eliminated.
The solutions are:
X = 4.714285714285714
Y = 1.1428571428571428
