Math Problem Statement

Set up the equation for the following word problem and solve the equation. Let x be the unknown number.

8484 times a number minus 6969 is equal to 1414 less than the number.

Solution

Let's start by translating the word problem into a mathematical equation.

Problem Breakdown:

  • "8484 times a number" can be represented as 8484x8484x.
  • "minus 6969" means subtract 6969 from the expression, so we have 8484x69698484x - 6969.
  • "is equal to" indicates equality, so we set the equation equal to the next part of the statement.
  • "1414 less than the number" means x1414x - 1414.

Setting Up the Equation:

The equation based on the problem statement is:

8484x6969=x14148484x - 6969 = x - 1414

Solving the Equation:

  1. Subtract xx from both sides to get all xx-terms on one side:

8484xx6969=14148484x - x - 6969 = -1414

  1. Simplify the equation:

8483x6969=14148483x - 6969 = -1414

  1. Add 6969 to both sides to isolate the xx-term:

8483x=55558483x = 5555

  1. Divide both sides by 8483 to solve for xx:

x=55558483x = \frac{5555}{8483}

Final Answer:

x=555584830.6547x = \frac{5555}{8483} \approx 0.6547

So the unknown number xx is approximately 0.6547.

Here are some related questions:

  1. How would the equation change if the constant 6969 were instead added?
  2. What if the phrase "is equal to" was replaced with "is greater than"?
  3. How would you set up the equation if the problem involved two unknown numbers?
  4. What if 1414 was greater than the number instead of less?
  5. How does the equation change if the multiplication by 8484 was instead division?

Tip: Always carefully translate word problems into equations by identifying operations and relationships.
