The sum of the larger and smaller number is 15.

Step-by-step explanation:

Let x = smaller number

Let y = larger number

Set up a system of equations.

2y - x = 21

2y + x = 27

Add the two equations together to cancel out x

4y = 48

Divide both sides by 4

y = 12

Plug value into either equation to find x

2(12) - x = 21

24 - x = 21

x = 3

12 + 3 = 15
