How do I write a real world problem that could be solved using the equation x+287 = 594

Real-world problem using the equation x + 287 = 594 ...

Let's suppose you have $287 dollars in your bank account. You deposit a check and afterwards have $594 in your account. How much was the check worth?

You can then find the answer by solving for x:

594 - 287 = x

594 - 287 = 307

x = 307

So the check was worth $307!
