Just checking in case I read the language wrong. Here's what I did:\[-55-85-75=-215\]as in: $215 dollars overdrawn

@supie opinion pls. ? ty

Answer 4

That's correct.

You can think of the original overdrawn balance as 'x'
Even after depositing 85 and 75 dollars, his account was still overdrawn by 55 dollars (so he had a balance of -55)

So we have
x + 85 + 75 = -55

And to solve for x, it would then be just like how you set it up

x = -55 - 85 - 75 = -215

So good job!
