You have the following information:

- Allie owes her parents $43

- Lasth month She owed them 3 times as much, that is she owed

3 x $43 = $129

You can write the previous situation with negative integers, as follow:

you consider the debt as a negative quantity:

Allie owes her parents $43 : - 43

She owed $129 = -129

If she owed $129 last month, this means she payed $129 - $43 = $86 to her parents this month. Then, she payed $83 = + 83

Summarizing, you have:

- 129 + 83 = - 43
