Question

5(f+2) = 2(3-f)

I don’t quite understand this well our teacher is having us try new stuff and if possible would anyone be so kind as to teach me?

Answer 1

First off distribute so 5(f+2) is converted to 5f+10 and 2(3-f) into 6-2f after we get rid of the variable on one side so let’s add 2f to 5f+10 and we are left with 7f+10=6 now Subtract 10 from 6 and we get 7f=-4. Divide by 7 to get f by itself and the final answer is -1.75
