Answer:
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+57---------------2
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
