This clever math puzzle looks simple, but it tests whether you remember the basics of solving equations. You’re given two expressions:
a + b = 80
a − b = 40
The challenge is to determine the value of a ÷ b. Many people try to guess, but the fastest method is to solve the system step by step.
Add the first two equations together:
(a + b) + (a − b) = 80 + 40
This gives 2a = 120, so a = 60.
Substitute 60 into the first equation:
60 + b = 80
This means b = 20.
Finally, divide the two values:
60 ÷ 20 = 3.
The correct answer is **3**. Puzzles like this are a great way to practice algebra while improving logical thinking and problem-solving skills.
