Explore the concept of equality in mathematics through real-world examples and problems. We begin with the question: what does it mean for two quantities to be equal? Using the case of an angelfish and a clown fish, we illustrate the Subtraction Property of Equality to find the length of the clownfish. Additional examples, such as calculating temperatures and the costs of clothing items, demonstrate the Addition Property of Equality in action. Learn how to use equations to solve everyday problems efficiently!

  1. Solving Equations Essential Question: What does it mean to say two quantities are equal?

  2. Real World Example An angelfish can grow to be 12 inches long. If an angelfish is 8.5 inches longer than a clown fish, how long is a clown fish?

  3. Check it out! An angelfish is 8.5 inches longer than a clown fish Let c represent the length of the clown fish 12 = c + 8.5 -8.5 -8.5 3.5 = c The clown fish is 3.5 inches long

  4. Subtraction Property of Equality The subtraction Property of Equality states that the two sides of an equation remain equal when you subtract the same number from each side. If a = b, then a – c = b – c.

  5. Got it? Do this problem to find out. The highest recorded temperature in Warsaw, Missouri, is 118°F. This is 158° greater than the lowest recorded temperature. Find the lowest recorded temperature.

  6. Another example A pair of shoes costs $25. This is $14 less than the cost of a pair of jeans. Find the cost of the jeans. Let j represent the cost of jeans.

  7. Addition Property of Equality The Addition Property of Equality states that the two sides of an equation remain equal when you add the same number to each side. If a = b, then a + b = a + c

  8. Real World Example Jessica sent 574 text messages last week. On average, how many messages did she send each day?

  9. Check it out! Let m represent the number of messages Jessica sent. 574 = 7m 574 = 7m 7 7 82 = m Jessica sent 82 messages on average each day.

  10. Try another… The distance d Diana travels in her car While driving 60 miles per hour for 3 hours is given by the equation . How far did she travel?

  11. Check it out! Diana traveled 180 miles.
