Question

7f+g=5, for f just answer

Answer 1

All you have to do is subtract g on both sides and divide by coefficient of f. Let me know what you get!

Answer 2

f=5/7+g/7 ?

Answer 3

7f+g=5
7f = 5 - g
(1/7) (7f) = (1/7) (5 - g)
f = (5 - g)/7 = 5/7 - g/7

Answer 4

No! It's f=5-g/7
You need to subtract g and divide by 7.

Answer 5

you need to divide 5 by 7 too

Answer 6

Yup but if you need to safe a bit of lead, you can put the whole thing on top of 7 (:
