Question

In an algebraic expression, a single variable can be used to represent two different missing numbers/values.

• A. True
• B. False

Answer 1

The correct option is B False

• In an algebraic equation, different variables are used to show/ indicate different missing values/numbers.
• Suppose Rakesh bought bananas and mangoes and the quantities are unknown. So, now we can represent the number of bananas by variable x and the number of mangoes by variable y.
• Any variable used in a linear equation can have only one value and represents the same unknown through the entire equation . Hence in this case bananas and mangoes represent two different unknowns and hence has to be represented by two different variables.
