Topics in Linear Equations in Two Variables
1
Introduction to Linear Equations in Two Variables
- A linear equation in two variables has the general form ax + by + c = 0, where a, b, c are real numbers and a, b are not both zero
- The degree of both variables in a linear equation is 1
- A single linear equation in two variables has infinite solutions
2
Simultaneous Equations
- When two linear equations in two variables are considered together, they are called simultaneous equations
- Simultaneous equations may have: (1) Unique solution, (2) No solution, or (3) Infinite solutions
- The common solution satisfies both equations simultaneously
3
Elimination Method
- Eliminate one variable by making coefficients equal and adding or subtracting equations
- Multiply equations by suitable numbers to make coefficients of one variable equal
- After eliminating one variable, solve for the remaining variable
4
Substitution Method
- Express one variable in terms of the other from one equation
- Substitute this expression into the second equation
- Solve the resulting equation in one variable
