  How can you count the solutions to an equation without solving it? In this lesson, we work through three examples, including TMUA 2022 Paper 1, Question 20, and explore how rearranging an equation can make the graphs easier to sketch and their intersections easier to count.

  • Graph sketching
  • Number of solutions
  • Modulus functions
