Best ResponseYou've already chosen the best response.13x + 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 ?

Best ResponseYou've already chosen the best response.1Is the new equations 6x+8y=4 and 6x+9y=30? Or did I do something wrong?

Best ResponseYou've already chosen the best response.1now add the 2 equations 6x+ 8y=4 6x+ 9y=30

Best ResponseYou've already chosen the best response.1Like this? 6x9y=30 or is it like this? 6x(9y)=30?

phi

Best ResponseYou've already chosen the best response.1are 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

Best ResponseYou've already chosen the best response.1Then, you add them and the 6's cancel out right? Then you would have 0x+17y=34 right or would it be a ?
