Question

Can we subtract unlike terms in an algebraic expression?

• A. Yes
• B. No

Answer 1

The correct option is B No

Addition and subtraction can be performed only on like terms of an algebraic expression.
For example, we can add or subtract the like terms $5x$ and $2x$.

We cannot add or subtract unlike terms of an algebraic expression e.g. $3y$ and $8z$, because of different literal variables.
Therefore, option (b.) is the correct answer.
