The sum of two numbers is 20. the difference of the two numbers is twice the smaller number. what are the two numbers?

x = 15 ; y = 5

Step-by-step explanation:

x + y = 20

x - y = 2*y

x = 20 - y

20 - y - y = 2*y

20 - 2*y = 2*y

- 2*y - 2*y = -20

- 4*y = -20

y = -20 / -4

y = 5

x + y = 20

x + 5 = 20

x = 20 - 5

x = 15
