Step 1)

We know that together they have $360 and that John has twice as much as Peter. We want to find the individual amounts of money.

------------------------------------------------
Step 2)

Let J = amount of money that John has and P = amount of money Peter has

------------------------------------------------
Step 3)

Since "John has twice as much money as Peter", we know that John's dollar amount is equal to 2 times Peter's dollar amount. So the first equation is .

Also, since we know that "together they have $360", this means that the sum of their money is 360. So the second equation is

------------------------------------------------
Step 4)

Start with the second equation.

Plug in

Combine like terms on the left side.

Divide both sides by to isolate .

Reduce.

So Peter has $120

Go back to the first equation

Plug in

Multiply

So John has $240

------------------------------------------------
Step 5)

Check:

Notice how John's dollar amount is twice that of Peter's.

Also, notice how the sum of their money is: 240+120 = 360, so this verifies the second condition.

So this verifies the answer.

The positive numbers, the negative numbers, and zero make up the real Numbers.
