well you need the same coefficient for y if you want them to cancel. in the first one the coefficient of y is 1. and in the second it's 2. so 1 x ? = 2

1 x 1 = 2 ?

You would the first equation by 2, getting 6x 2y = 6. when added to second equation the y's would "add out" or their sum is 0.

I left out the word multiply, which goes in the first sentence between " would * the"

As I have previously posted, if you want to eliminate the y's, multiply the first equation by 2. this gives you: 6x 2y = 6 Now add the 2nd equation 2x+2y =6  4x = 12 x=3

Now you can solve for y.

@radar is right cause your supposed to Solve it using the addition method.

Substituting for x in the 2nd equation getting 2(3) + 2y = 6 6 +2y = 6 2y= 12 y=6 x=3, y=6 To be sure check them out

@radar, what is it about "I found my MISTAKE" did you not understand?

It never hurts to verify substituting 3 for x, 6 for y 3xy=3 or 3(3)6=3 96=3 3=3 first one checks! 2x+2y=6 2(3)+2(6)=6 6 +12 = 6 6=6 checks

No need to persist. Be happy that you provided the right solution and move on.

@Hero, just wanted to verify my answer, so I was simply asking if you got the same (after your error discovery.

When I said I found my mistake, that implies that I acknowledge your correct answer. Furthermore I gave you a medal. As I said, no need to persist beyond that.
