Question

How do you solve `d - 65.24 = 347.81`?

Answer 1

`d=413.05`

Explanation:

We have `d-65.24=347.81`

Now adding `65.24` on both sides, we get

`d-65.24+65.24=347.81+65.24`

`d-cancel(65.24+65.24)=347.81+65.24`

or `d=413.05`

Answer 2

The solution is `d = 413.05`, steps are in explanation.

Explanation:

`d - 65.24 = 347.81` This is our given equation

We need to find a way to get `d`, the variable, by itself, so that it can equal a solid answer. To do that, we need to isolate the variable.

`d = 347.81 + 65.24` *We isolated `d` by using the inverse of subtraction, addition, and added `65.24` to both sides.

Now `d` is isolated, and we have all our numbers on one side of the equal sign. Use a calculator or manually compute `347.81 + 65.24`.

`d = 413.05`

And yo have your answer!

Answer 3

`d = 413.05`

Explanation:

Treat an equation as a balance.
What is on one side is exactly equal to what is on the other side, so the balance will stay level.

You can do anything you like to an equation - ADD, SUBTRACT, MULTIPLY,DIVIDE, etc as long as...

YOU MUST DO THE SAME ON BOTH SIDES.

In `d - 65.24 = 347.81`, we would like to have `d` = a number.

To get rid of -65.24, add on 65.24.
(-65.24 +65.24 = 0)
But we must add 65.24 to BOTH sides.

`d - 65.24 color(red)(+65.24)= 347.81color(red)(+65.24)`

`d = 413.05`

By doing the opposite on both sides, this has had the effect of 'moving' the 65.24 from the left to the right side.
