The easiest way to do this is to plug in the numbers for the variebles and see if they equal the same in both sides. lets try the first one 5(1)+2(3)=1, multiply the nmbers to get 56=1 now simplify to get the answer of 1=1, they both equal the same so this means that the first option is the correct one
Hope this helps

Plug the x and y values in and see which one equals 1.
5x + 2y = 1
A. 5(1) + 2(3) = 5 = 6 = 1
B. 5(1) + 2(4) = 5 + 8 = 3
C. 5(2) + 2(4) = 10  8 = 2
D. 5(2) + 2(5) = 10 + 10 = 0
The answer is A
