On thursday, a local hamburger shop sold a combined total of 351 hamburgers and cheeseburgers. the number of cheeseburgers sold was two times the number of hamburgers sold. how many hamburgers were sold on thursday?

X is cheeseburgers and y is hamburgers x + y= 351 2x+y=351 Now I can do 351 divided by 3 which gives me 117. Since 117+117+117 is 351 and the number of cheeseburgers sold was twice the amount as hamburgers. I will say that there was 117+117 cheeseburgers sold and there were 117 hamburgers sold. Hope it makes sense

 If there are only two options, and one is double of the other, then one is 2/3 and the other is 1/3 of the question (total being 3/3, or one whole) So...351/3=117, so 117 hambergers were sold.117*2=234, so 234 cheeseburgers were sold

You would have to multiply all of the numbers

The equation is y=17(7)+600 and it equals 717
