Case Study 3: Linear Equations in Two Variables
A fruit seller sells apples and oranges. The cost of one apple is Rs. 20 and the cost of one orange is Rs. 10. On a certain day, the seller sold a total of 40 fruits, and the total collection was Rs. 600. Let the number of apples be \(x\) and the number of oranges be \(y\). Then the problem can be modeled using linear equations in two variables. The two equations are derived from the conditions of total fruits and total revenue.
In general, linear equations of the form \[ a_{1}x + b_{1}y + c_{1} = 0, \] \[ a_{2}x + b_{2}y + c_{2} = 0, \] can be solved algebraically (substitution or elimination method) or graphically. Such problems are widely used to represent real-life conditions.
Key Concepts:
- A linear equation in two variables represents a straight line on a graph
- A system of two linear equations can have a unique solution, no solution, or infinitely many solutions
- The ratio \(\frac{a_1}{a_2} \neq \frac{b_1}{b_2}\) indicates a unique solution
- Real-world problems can be modeled using linear equations
