The directions are to create an expression that represents two unknown numbers for which I will use "x" & "y" to represent them. How can I write an expression for their sum in terms of just X
So since it's asking for an expression for the sum of the two unknown numbers I know the expressions that I need to create will have a "+" but I can't show the expression in terms of just "x"
I was thinking that:
f(x)=x+y
or...
f(x)=1/y
or...
f(x)=1/x
I don'rt know, I'm lost because I don't understand the part of the question that asks for the sum in terms of just "x" ....
