A local hamburger shop sold a combined total of 568 hamburgers and cheeseburgers on Saturday. There were 68 more cheeseburgers sold than hamburgers.

How many hamburgers were sold on Saturday?

Use algebra:

Let x be the number of burgers sold.

We know that then for a fact that:

x + (x+68) = 568

Since the number of total burgers sold is 568

Then, we know that:

2x + 68 = 568

Subtract 68 from both sides:

2x = 500

Divide both sides by 2,

Answer is 250
