Key Topics to Revise

1

Linear Equations in One Variable

  • A linear equation in one variable has the form ax + b = 0, where a ≠ 0
  • The solution is the value of variable that satisfies the equation
  • Use balance method: perform same operation on both sides
2

Word Problems in One Variable

  • Identify unknown quantity and assign variable
  • Translate given conditions into algebraic equation
  • Solve the equation systematically
3

Linear Equations in Two Variables

  • General form: ax + by + c = 0 where a, b are not both zero
  • Has infinitely many solutions (ordered pairs)
  • Each solution is a point (x, y) on the coordinate plane
4

Systems of Linear Equations - Graphical Method

  • System has two equations with same two variables
  • Solution is intersection point of two lines
  • Three cases: unique solution, no solution, infinitely many solutions
