The sum of two numbers is 36. Twice the first number minus the second is 6. Find the numbers

14 and 22 are the two numbers in question

{ x + y = 36

{ 2x - y = 6 (Cancel + y - y = 0)

x + 2x = 36 + 6

3x = 42

x = 42

3

x = 14

Substitute x for 14 in one of the equations:

x + y = 36

14 + y = 36

y = 36 - 14

y = 22

Solution: { 14, 22 }
