Best ResponseYou've already chosen the best response.0The substitution method means you solve one equation for a variable and then plug that solution into the other equation for that variable.

Best ResponseYou've already chosen the best response.0so n = 13m m5(13m) = 11 m5+15m = 11 16m = 16 m=1. n = 13(1) = 2 n=2

Best ResponseYou've already chosen the best response.0What are you confused on? Once you have your answers i.e m=1 and n=2 you can write them as an ordered pair.

Best ResponseYou've already chosen the best response.03m + n = 1 subtract 3m from both sides n=13m what r u confuzed about?

Best ResponseYou've already chosen the best response.0So (n,m) could be a pair or (m,n) depends on which one is independent and dependent.

Best ResponseYou've already chosen the best response.0He is just solving for one of the variables if that is what you are asking. You want to get one of the variables in terms of the other so you will have an equation with only one unknown that you can solve for. He could have done 3m=1n and then divided by 3 to solve for m and plug in into the other equation.

Best ResponseYou've already chosen the best response.0is that what i suppossed to do, then that equation would become n = 13m

Best ResponseYou've already chosen the best response.0That is how you would solve the first equation for n. Now you would replace n in the other equation with your "new" n=13m so m5(13m)=11

Best ResponseYou've already chosen the best response.0m  5(13m) = 11 this correct? then I would make it 5  16m = 11

Best ResponseYou've already chosen the best response.0The first part is correct, but the second part I believe you messed up on your signs. Should be 5+16m=11

Best ResponseYou've already chosen the best response.0Add 5 to both sides to get 16m=16 divide both sides by 16 to leave m=1

Best ResponseYou've already chosen the best response.0oh I thought I would have to subtract 5 from both sides not add, this is where I get confused on knowing which to do , add or subtract

anonymous

Best ResponseYou've already chosen the best response.0Since the 5 is negative, you want to perform the opposite operation to get it on the other side. If the 5 was positive you would subtract it from both sides.
