Question

State which of the following are equations (with a variable). give reasons for your answer. Also mention which variable is used from the equations with a variable

$(9\times 3)+2=(3\times 6)+9$

Answer 1

An equation is a mathematical statement containing an equal sign which shows that two expressions are equal.

As, $(9\times 3)+2=(3\times 6)+9$, has $=$sign, so it is a statement of equality but it has no variable.

Hence, it is not an equation with a variable.
