use substitution to solve system of equations? y=x+5  3x+y=25

I got  f
is a function since each element of A in the first place in the ordered pairs
is related to only one element of A in the second place while
g
is not a function because
1 is related to more than one element of A, namely, 2 and 3


is it correct.
