Substitute 1 for x in each of your equations.
f(x)=7-3x
which is
f(1)=7-3(1)
=3
Do the same for g(x)
g(x)=3x-7
which is
g(1)=3(1)-7
=-4
Then subtract g(x) from f(x):
3-(-4)
=7

Range is the greatest number minus the smallest number
The greatest number is 67
The least number is 19
67 - 19 = 48
48 is your range
hope this helps
