PLEASE HELP
Two equations are given below:
m + 4n = 8
m = n − 2
What is the solution to the set of equations in the form (m, n)?
(4, 6)
(2, 4)
(0, 2)
(6, 8)

Best ResponseYou've already chosen the best response.1first, let's leave the second equation alone for now and just look at m+4n = 8 what do you get when you subtract 4n from each side?

Best ResponseYou've already chosen the best response.1hm, not quite, let's just try the left side first what happens when you subtract 4n from m+4n?

Best ResponseYou've already chosen the best response.1right! now let's look at the right side what happens when you subtract 4n from 8?

Best ResponseYou've already chosen the best response.1nope, since 8 has no variable and 4n has a variable, it's just 8  4n understand so far?

Best ResponseYou've already chosen the best response.1ok, so the left side of the equation is m, and the right side of the equation is 8  4n, which gives us m = 8  4n with me so far?

Best ResponseYou've already chosen the best response.1good, so our first equation is m = 8  4n and our second equation is m = n  2 we have m by itself on the left side in both equations, so we can set the two equations equal to each other 8  4n = n  2 can you try solving for n now?

Best ResponseYou've already chosen the best response.0I thing so would it be 4,6

Best ResponseYou've already chosen the best response.1not quite, let's just take this one step at a time 8  4n = n  2 what happens when you add 2 to each side?

Vocaloid

Best ResponseYou've already chosen the best response.1add 2 to the left side, add 2 to the right side, and tell me what is on each side

Best ResponseYou've already chosen the best response.1not quite, remember we want to leave 4n and n alone because these are variables

Best ResponseYou've already chosen the best response.1left side is 8  4n, what do you get when you add 2?

Vocaloid

Best ResponseYou've already chosen the best response.1great! the right side is n  2, what do you get when you add 2?

Best ResponseYou've already chosen the best response.1not quite, what is n2+2?

Vocaloid

Best ResponseYou've already chosen the best response.1not quite, think of it this way n2+2 means start with n, take away 2, then add 2 back what is n2+2?

Vocaloid

Best ResponseYou've already chosen the best response.1not quite, remember that we leave n alone since its a variable one more time n2+2=?

Best ResponseYou've already chosen the best response.0so basicly we just substract 2 from to then add it back correct

Best ResponseYou've already chosen the best response.1right, so what do we get in the end?

Best ResponseYou've already chosen the best response.1uh, not quite... let me try to explain it differently I start with n marbles. I pick up 2 marbles, then I drop 2 marbles. How many marbles do I have?

Best ResponseYou've already chosen the best response.1hint: I started with n marbles

Best ResponseYou've already chosen the best response.1right! so what does n2+2=?

Vocaloid

Best ResponseYou've already chosen the best response.1good! so, on the left side we have 104n and on the right side we have n 104n = n now, let's leave 10 alone since it's not a variable what happens when we add 4n to each side?

Vocaloid

Best ResponseYou've already chosen the best response.1not quite... the left side is 104n, what do we get when we add 4n?

Vocaloid

Best ResponseYou've already chosen the best response.1not quite, please try again 104n+4n=?

Vocaloid

Best ResponseYou've already chosen the best response.1not quite, remember that we leave the 10 alone since it's not a variable (doesn't have n) 104n+4n = ?

Best ResponseYou've already chosen the best response.0oh so 104n+4n=108n

Best ResponseYou've already chosen the best response.1not quite... think of it this way: I start with 10, take away 4n, then add 4n. what's left?

Best ResponseYou've already chosen the best response.1not quite, let's try one more time I start with 10 marbles, then I drop 4n marbles, then I pick up 4n marbles, how many marbles do I have?

Best ResponseYou've already chosen the best response.1let's try something different 104+4=?

Vocaloid

Best ResponseYou've already chosen the best response.1so, if AB+B = A, then what is 104n+4n?

Best ResponseYou've already chosen the best response.1great! so, the left side is 10 now let's move to the right side the right side is n, what do you get when you add 4n?

Vocaloid

Best ResponseYou've already chosen the best response.1not quite, remember that we started with n n+4n=?

Best ResponseYou've already chosen the best response.0oh so we just add 4 to the N

Best ResponseYou've already chosen the best response.1not quite... hint: n+4n = (1+4)n

Best ResponseYou've already chosen the best response.0oh so the thing is 5n

Vocaloid

Best ResponseYou've already chosen the best response.1great! left side is 10 right side is 5n 10 = 5n can you try solving for n now?

Best ResponseYou've already chosen the best response.0I think it would equal 0,2

Vocaloid

Best ResponseYou've already chosen the best response.1great! n = 2 going back to the original problem, m = n − 2 so what is m?

Vocaloid

Best ResponseYou've already chosen the best response.1great! m=0 n=2 so what is (m,n)?
