4-5f=64 subtract 4 on both sides to isolate 5f. 4-4 cancels out and 64-4 is 60

-4 -4

-5f=60 divide both sides by -5 to isolate f. -5/-5 cancels out and 60/5 is 12

/-5 /5

f=12 now f is isolated and the solution on the other side is 12!

You should now how to solve equations by now unless your mentally retarded btw.
