Waiting room

In the waiting room are people and flies. Together they have 15 heads and 50 legs (fly has 6 legs). How many people and flies are in the waiting room?

Correct answer:

x =  5
y =  9

Step-by-step explanation:

x+y=14 2x+6y=64 x=5
y=9

x+y=14; 2x+6y=64

x+y=14
2•x+6•y=64

x+y = 14
2x+6y = 64

x = 5
y = 9
