Expressions, Equations and Inequalities

What is an inequality?

• treating two numbers the same

• the relation between two expressions that are not equal

• an inverse operation

What is a solution set?

• a set of values that do not satisfy a given set of equations or inequalities

• the solution to an inequality

• the set of values that satisfy a given set of equations or inequalities

What is the definition of one solution?

• no matter what constant is substituted in for the variable, the equation is ALWAYS true

• only this ONE solution will make the equation true

• no matter what constant is substituted in for the variable, the equation will NEVER be true

"Twenty-four minus three times an integer, x, is less than x minus four."

Write an inequality, in terms of x, to represent this information.
