Question
The cost of ball pen is Rs 5 less than half of the cost of fountain pen. Write this statement as a linear equation in two variables.
Solution
Let's break down the given information step by step:
Step 1: Let's assume the cost of the fountain pen is represented by the variable "x".
Step 2: The cost of the ball pen is Rs 5 less than half of the cost of the fountain pen.
Step 3: Half of the cost of the fountain pen is represented by the expression "x/2".
Step 4: Rs 5 less than half of the cost of the fountain pen is represented by the expression "x/2 - 5".
Step 5: Therefore, the linear equation in two variables representing the given statement is: Cost of ball pen = x/2 - 5
In this equation, "x" represents the cost of the fountain pen and the expression "x/2 - 5" represents the cost of the ball pen.
