Solving Equations by Adding or Subtracting

• You solve equations with fractions by using inverse operations, adding or subtracting, to isolate the variables.
• Solving equations with fractions is similar to solving equations with integers and decimals; use the properties of equality to isolate the variable.
• Remember to add and subtract fractions using the least common denominator. Create equivalent fractions with common denominators by multiplying both the numerator and denominator by the same number. Always write the answer in simplest form.
