Answer:

x=5, y=2

Step-by-step explanation:

Double one number plus triple another number equals 16, and six times the first minus five times the second equals 20. Calculate both numbers

2x + 3y = 16

6x - 5y = 20

3 * (2x + 3y) = 3 * 16

6x + 9y = 48

(6x + 9y ) -(6x - 5y) = 48 - 20

14y = 28

y = 2

x = 5
