17n + 4n- 4= 122<br><br> how do i solve for n?
Leokris [45]

Help i am in need of help
makvit [3.9K]

You can start by writing equations with the given information

1) You know that together, Mindy and Troy ate 9, so you can write

M+T=9

2) Then, it says that Mindy ate 3, so M=3

3) Troy ate 1/4 of the total cake, however we don't know what the amount of the total cake is, so we can represent it as x, T=1/4x

4) Plug in these equations into the first equation, 3+1/4x=9

5) Solve for X, Subtract 3 from both sides to get 1/4x=6

6) Divide 1/4 on both sides, x=(6÷1/4)

x=24

Hope this helped :)
