For Mathematics

I can start by doing my homework first and not procrastinating.

Chapter 4: Algebra Puzzle

My solution (Method 1):
3 Pears = 27
Therefore, 1 Pear represents 9.
2 Pears + 1 Umbrella = 24
Since 1 Pear represents 9,
18 + 1 Umbrella = 24
Therefore, 1 Umbrella represents 6.
2 Umbrellas + 1 Apple = 25
Since 1 Umbrella represents 6,
12 + 1 Apple = 25
Therefore, 1 Apple represents 13.
So, 1 Pear = 9
      1 Umbrella = 6
      1 Apple = 13
