Question

Rearrange e = 2f to make fthe subject.
=

Answer 1

f=e/2

Explanation:

To make f the subject, we want to isolate f.

e=2f.

We see that e is equal to two times f, or two f's.

Divide by 2 to isolate f.

e/2=f

However, normally we want f on the left side, so we have:

f=e/2

Answer 2

f = e/2

Explanation:

e = 2f

Switch sides.

2f = e

Divide both sides by 2.

f = e/2
