Question

How do you 92 = 8(f + 2) – 4 ?????

Answer 1

Based on my calculation i know for sure F
would equal 10

Answer 2

Hey. Well, to answer this question, it is simply reversing the processes to find out what f is equal to. Essentially, you want to get f all by itself so we can find out what it is.

92 = 8(f+2)-4

92+4 = 8(f+2)             ------ (Add 4 to both sides.)

96 = 8(f+2)                ------- (ONE STEP CLOSER! Now, divide both sides by 8)

12 = f+2                    ------(Looking good. Go on and subtract 2 from both sides.)

f = 10                  

Super cool. It's just to reverse whatever is done on the other side. If 2 is added on one side, go on and subtract it!

If you want to check, just go on and plug 10 into f in the original equation. It comes to 92!
