Question

Choose the constant that could be multiplied by each equation to create a system of equivalent equations with opposite terms.

2x + 3y = 1
5x + 2y = 8

The first equation can be multiplied by 5 and the second equation by 2.
The first equation can be multiplied by –5 and the second equation by –2.
The first equation can be multiplied by –5 and the second equation by 2.

Answer 1

The 3rd one

Explanation:

Answer 2

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).

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.
