Alocal hamburger shop sold a combined total of 507 hamburgers and cheeseburgers on thursday. there were 57 more cheeseburgers sold than hamburgers. how many hamburgers were sold on thursday?

282 cheeseburgers         225 hamburgers

Step-by-step explanation:

for solution let x be hamburgers

y be cheese burgers

as we know that 57 more cheese burgers are sold than hamburgers, so hamburgers ca be written as

x+y=507 1

y=x+572

adding value of y in equation 1

x+(x+57)= 507

2x+57=507

2x=507-57

2x = 450

x= 450/2

x=225 hamburgers

now for cheese burgers , add value of x in equation 2

y=x+57

y=225+57

y=282 cheeseburgers

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
