Day 7

Spaced Revision

Come back to Linear Equations in one Variable after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • An equation states that two algebraic expressions are equal.
  • A linear equation has only one variable and the highest power of the variable is 1.
  • A linear equation has only one solution, called its root.
  • Keep both sides balanced at every step.
  • Use inverse operations to isolate the variable.
  • Use the L.C.M. to clear fractions in many equations.
  • Use the L.C.M. to clear denominators when fractions appear in an equation.
  • Cross-multiplication is useful for fraction equations of the form a/b = c/d.
  • Write the cross-products carefully.

Common Mistakes to Avoid

Any statement with an equal sign is a linear equation.

The variable in a linear equation must be positive or a natural number.

When moving a number across the equal sign, its sign stays the same.
