Question

Which of the following is/are not algebraic equation(s)?

• A. $3x+6$
• B. $3x+6=9$
• C. $4x=12$
• D. $2x+10$

Answer 1

Answer: (A), (D)

The correct options are
A $3x+6$
D $2x+10$

An algebraic equation has a LHS and a RHS equated with an '=' symbol.
An algebraic equation has an algebraic expression equated to something.

Therefore, $3x+6=9$ and $4x=12$ are algebraic equations.

However, $3x+6$ and $2x+10$ are just expressions and not equations since they are not equated to anything.

Hence, $3x+6$ and $2x+10$ are just algebraic expressions and not algebraic equations.
