Understanding Fiona’s Techniques

Simplifying Expressions

  • Fiona begins by simplifying both sides of the equation, removing parentheses, combining like terms, and carrying out any necessary mathematical operations.
  • Simplifying expressions reduces the complexity of the equation, making it easier to isolate variables in subsequent steps.

Isolating Variables

  • Once the equation is simplified, Fiona isolates the variable she wants to solve for on one side of the equation.
  • She performs inverse operations to eliminate any coefficients or constants that are multiplied or divided by the variable.

Utilizing Mathematical Properties

  • Fiona leverages various mathematical properties throughout the equation-solving process.
  • These properties include the additive inverse, multiplicative inverse, and distributive property, which allow her to manipulate equations while preserving their equality.

Fiona’s Proven Strategies

Eliminating Variables by Substitution

  • If an equation contains multiple variables, Fiona employs the method of substitution.
  • She substitutes one variable with an equivalent expression, reducing the equation to a one-variable equation, which is easier to solve.

Using Quadratic Formula

  • For quadratic equations, Fiona utilizes the quadratic formula, a general formula that provides two solutions to a quadratic equation.
  • This formula is especially useful when the equation is in factored form or cannot be factored easily.

Solving Rational Equations

  • Fiona approaches rational equations by finding the least common multiple (LCM) of the denominators.
  • She then multiplies both sides of the equation by the LCM, clearing the fractions and simplifying the equation into a linear equation.

Real-World Applications

Balancing Chemical Equations

  • Fiona’s equation-solving skills extend to the field of chemistry, where she uses them to balance chemical equations.
  • By solving for the coefficients in the equation, she ensures that the number of atoms of each element is the same on both sides of the equation, reflecting the law of conservation of mass.

Solving Physics Problems

  • In physics, Fiona applies her equation-solving abilities to solve problems involving kinematics, dynamics, and other concepts.
  • She uses equations to model physical phenomena and determine unknown variables, such as velocity, acceleration, and force.


Fiona’s systematic approach to solving equations empowers learners with the essential skills to tackle a wide range of mathematical challenges. By following her techniques, you can develop your ability to simplify expressions, isolate variables, and utilize mathematical properties. Whether you’re a student, a professional, or simply someone who enjoys tackling brain-teasers, Fiona’s methodologies will guide you toward successful equation-solving. Embrace her wisdom, practice consistently, and you will undoubtedly become a formidable equation solver yourself.
