Solution:

  1. Convert into slope-intercept form
  2. Plot points on the graph
  3. Find the intersection point

๐Ÿ“ข Conclusion: The solution is x = 3, y = 0.

Exercise 3.2: Substitution Method

โœ” Step 1: Express one variable in terms of the other.
โœ” Step 2: Substitute in the second equation.
โœ” Step 3: Solve for both variables.

๐Ÿ“Œ Example: Solve

  1. x + y = 14
  2. x โ€“ y = 4

Solution:

๐Ÿ”น Final Answer: (9, 5)

Exercise 3.3: Elimination Method

โœ” Add/subtract equations to eliminate one variable.
โœ” Solve the remaining equation.
โœ” Substitute back to get the second variable.

๐Ÿ“Œ Example: Solve

  1. 3x โ€“ 5y = 4
  2. 9x = 2y + 7

โœ… Graphical Solution & Explanation

Exercise 3.4: Cross Multiplication Method

โœ” Formula-based approach
