How many variables can be found in the expression: $4x+5y+3$?

• A. 1
• B. 2
• C. 3

Answer 1

The correct option is B 2

The word ‘variable’ means something that can vary or change. The value of a variable is not fixed. It can take different values.

In the given expression $4x+5y+3$, the only variables we can find are $x$ and $y$. Their value is not fixed and can vary.
