Is it together or are they two separate problems?

3x + 4y = 2 2x  3y = 10 one way is to multiply the top equation (that means every term BOTH sides) by 2 and multiply the 2nd equation by +3 what do you get for the 2 new equations ?

Is the new equations 6x+8y=4 and 6x+9y=30? Or did I do something wrong?

close . redo the 2nd equation.

3*(2x3y)= 3*10 6x 9y = 30

now add the 2 equations 6x+ 8y=4 6x+ 9y=30

Like this? 6x9y=30 or is it like this? 6x(9y)=30?

are you asking what you get when you multiply the 2nd equation by 3 ? 2x + 3y = 10 3 times each term: 3*2x + 3* 3y = 3*10 there is only 1 minus sign, and it stays you get 6x 9y = 30

Oh, okay. I get it. Sorry, I got kicked off for a few minutes.

Then, you add them and the 6's cancel out right? Then you would have 0x+17y=34 right or would it be a ?

Okay, thank you so much for your help! I finally figured out the answer.
