Answer:
I think it's the third one. Because it will make both equation's x a opposite value (one is positive and one is negative).
Step-by-step explanation:
Because 2x+3y=1*5= 10x+15y=5 and then 5x+2y=8*-2 = -10x+4y=-16 both equations will cancel the Xs out and then you can solve for Y.
Answer:
18 I got it right
Step-by-step explanation:
on the test
17 + 15 + 26 = 58 (he wants 58 tickets)
22 - 8 = 14 (he has 14 tickets)
58 - 14 = 44 (he needs 44 tickets)
12 x .89 = 10.68
10.68 x 5= $53.40
answer is $53.40
13+2=15+1=16 that is the answer
