need help asap on math break even analysis

Question

Suppose a company has fixed costs of $30000 and variable cost per unit of

2/5x + 333 dollars, where x is the total number of units produced. Suppose further that the selling price of its product is 1363 − 3/5x dollars per unit.

Answer 1

A breakeven analysis is asking, "At what point does the company stop losing money and start making money?" To answer that question, you must set revenues and costs equal to each other. (The point at which revenues balance costs is the "breakeven point.")

However, the equations as written don't seem to make any sense. Here's why:

Total cost: 30000 + (2/5)x + 333

Total revenue: 1363 - (3/5)x

So...

30000 + (2/5)x + 333 = 1363 - (3/5)x

Add (3/5)x to both sides:

30333 + x = 1363

That means x = -28,970, which is a nonsensical answer. (X is the number of units sold, which can't be negative.) Are you sure the equations are written correctly?
