"Use a table"
?
Why? Is it necessary?


This is a system transcribed literally from the description:
system%28f%2Bb=56%2Cf-4=3%28b-4%29%29



steps:
f-4=3b-12
f-3b=-12%2B4
f-3b=-8

-
system%28f%2Bb=56%2Cf-3b=-8%29

b-%28-3b%29=56-%28-8%29
4b=64
highlight%28b=16%29
-
highlight%28f=40%29

10 and 46 ARE so INCORRECT. Try to do the problem yourself.

I'm certain you'll do a better job than the person who gave you a WRONG answer, which is a REGULAR THING for him!
