5+4-9​

Answer 1

To find:

Which of the following options is an equation.

Solution:

A mathematics or algebraic statement which represents that the values of two mathematical expressions are equal, is called an equation.

In option A,

`5-4=9`

`1\\eq 9`

LHS≠RHS. So, it is not an equation.

In option B and C,

`5+4=9`

`9=9`

LHS=RHS. Both are equations.

In option D,

`5+4-9`

This is an expression, not an equations.

Therefore, the correct options are B and C.
