A local hamburger shop sold a combined total of 712 hamburgers and cheeseburgers on Thursday. There were 62 more cheeseburgers sold than hamburgers. How many hamburgers were sold on Thursday?

x = hamburgers

y = cheeseburgers

x+y = 712

x + 62 = y

therefore

x+y = 712

x+x+62=712

2x = 712-62

2x = 650

x = 650/2

x= 325

y = x+ 62

y = 325+ 62

y= 387

The cheeseburgers sold were 387 and the hamburgers 325

your answer would be 10x - 1
