Question

anonymous · Answer

(-3(-3)+7)-(-7(3)+3)

anonymous · Answer

Hi welcome to Openstudy!

I would suggest that it would be easier for you to substitute all the values of x in the functions F(x) and g(x).
for example:
F(x)=-3x+7                        g(x)=-7x+3
F(-3)= -3(-3)+7                  g(3)=-7(3) +3

then after you solve for the values of x  from both functions, subtract the value of $g$ from the value of $f$
