Question

State the following is an equation (with a variable). Give a reason for your answer. Identify the variable from the equation with a variable.

$2\mathrm{m}<30$

Answer 1

Given, $2\mathrm{m}<30$

We know that an equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Since $2\mathrm{m}<30$ is not an equation as it does not have an equal sign$\left(=\right)$ between the expressions on LHS and RHS. It is inequality.

Therefore, $2\mathrm{m}<30$ is not an equation.
