A system of equations can have any number of inequalities.

Inequalities are not reflexive. Inequalities are not commutative.

Equations have and can only have a = Inequalities have <, >, greater than or equal to, less than or equal to, or =

Inequalities and equations are both the same because they are both mathematical expression and they both use the same steps EXCEPT for the end. Inequalities and equations are both different because equations have an equal sign, the answer is not an interval, and the answer is a specific answer. Not a range. While inequalities don't have an equal sign, its answer is an interval, and it's answer is in a range.

Solving inequalities and equations are the same because both have variables in the equation.

Linear equations or inequalities describe points x y that lie on a circle.

Equations and inequalities help maximize profit in a business by simultaneously optimizing the growth and profitability.

They both have variables.

If the equations or inequalities have the same slope, they have no solution or infinite solutions. If the equations/inequalities have different slopes, the system has only one solution.
