3x - 5y=-16
2x + 5y=31

A.(1/3, 1)

B.(5,3)

C.(8, 2)

D.(3 ,5)

Answer 1

alright
for this elimination easiest way is to add.
3x-5y=-16
+2x+5y=31
The result should be 5x=15 and x=3 plug into any original equation
2(3)+5y=31= 6+5y=31 5y=25 y=5

Answer 2

answer (3,5)

Answer 3

Oh, hah thank you

Answer 4

The reason we add in this case is becuz we have to eliminate something right? in this case if we add we would eliminate 5 and -5

Answer 5

oh..

Answer 6

it will get a little complicated later on when you get to different number where you have to multiply to get...you know the elimination process
