1. Put x= 2 and y = 2 in to each of the equations to see if they are true

C is the only one 2x-4y = -4 2(2) - 4(2) = 4-8 = -4 TRUE

2 Same thing here put x =6 and y = 4 into the equations to see which one is true

2x+3y = 20 ?

2(6) + 3(4) = 20?

12 + 12 = 20?

24 = 20? Nope...it is not 'a'......try the others to find the one that fits.....
