Suppose that 7 customers arrive, and each orders a different appetizer to share from a choice of 12 appetizers.

a in how many ways can this be done?
b. why is this answer the same as the number of ways that 5 customers can order different appetizers?

after simplifying it i got: -36.25 as my answer. hope that !

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
