Solve W = Fd for d

Step by step

The question

Question: solve for d in W = Fd.

We treat the other letters like numbers.

1 d on the left

d is on the right.

We swap the two sides, so d is on the left.

They are still equal.

2 Remove the F

Fd means F times d.

We want just d.

To remove times F, we divide by F.

We do it on both sides.

F divided by F is 1.

So just d is left.

So d = W over F.

3 Check

Let's check with numbers.

We pick F = 2, W = 4.

Our answer gives d = 2.

Now we put all the numbers into the start.

First the left side.

Now the right side.

Both sides are 4.

So our answer is right!

Let's look back.

First: d on the left.

Then: remove the F.

Last: check.
