# Please, classify the following as an equation, an inequality, or

Equation, expression, and inequalitie
$$\displaystyle\frac{{x}}{{2}}+{1}\le{3}{\left({x}+{7}\right)}$$
In $$\displaystyle\frac{{x}}{{2}}+{1}\le{3}{\left({x}+{7}\right)}$$ the expressions $$\displaystyle\frac{{x}}{{2}}+{1}{\quad\text{and}\quad}{3}{\left({x}+{7}\right)}$$ are joined with $$\displaystyle\le$$ inequality. It is obtained when an expression is related with another expression using the inequalities sign $$\displaystyle{\left({<},{>},\le,\ge\right)}$$.
That means, that$$\displaystyle\frac{{x}}{{2}}+{1}\le{3}{\left({x}+{7}\right)}$$ is an inequality.
