Question

The elves and reindeer are

Answer 1

Answer:

• 10 elves and 5 reindeer

Step-by-step explanation:

Let the number of elves be x and reindeer be y, then we have equations:

• x + y = 15
• 2x + 4y = 40

Simplify the second equation and subtract the first one:

• x + 2y = 20
• (x + 2y) - (x + y) = 20 - 15
• y = 5

Then find x:

• x = 15 - 5 = 10
