Solving Equations with Fractions Quiz

Equation Solutions

• The equation to solve is (\frac{x}{2} + \frac{y}{x+10} = \frac{3}{4}).
• Possible solutions can include various pairs of ((x, y)) that satisfy the equation.
• To check if a specific pair is a solution, substitute the values into the equation and verify if the left-hand side equals (\frac{3}{4}).
• Identifying a value that does not meet this condition indicates it is not a solution.

Finding (y) for Specific (x)

• Substitute (x = -5) into the equation (\frac{-5}{2} + \frac{y}{-5+10} = \frac{3}{4}).
• Calculate how (\frac{-5}{2}) is evaluated and then solve for (y) as follows:
  • (\frac{-5}{10} + \frac{y}{5} = \frac{3}{4})
  • Rearranging leads to finding (y).

Extensions of Number Sets

• Rational number extensions include all numbers that can be expressed as a fraction of integers, as well as certain additional numbers such as square roots or other algebraic numbers.
• Imaginary numbers are defined as (a + bi) where (i) is the square root of (-1), providing solutions to equations that lack real solutions.
• Integer extensions include rational numbers, where every integer can be expressed in fraction form.
• Natural number extensions may involve whole numbers, integers, and fractions, broadening the concept of counting.

Summary of Number Extensions

• Rational numbers extend to include irrational numbers.
• Imaginary numbers comprise a separate category outside the reals, essential in complex number theory.
• Whole numbers include all integers (positive, negative, and zero).
• Natural numbers can potentially expand into greater realms like integers and rational numbers.
