Question

a local hamburger shop sold a combined total of 750 hamburgers and cheeseburgers on tuesday there were 50 more cheeseburgers sold than hamburgers how many hamburgers were sold on tuesday

Answer 1

350 hamburgers

Explanation:

x = hamburgers

y = cheeseburgers

x + y = 750

y = x + 50

Using substitution:

x + (x + 50) = 750

2x + 50 = 750

2x = 700

x = 350

y = 350 + 50 = 400
