Lesson Review: An open sentence is a mathematical statement that contains two algebraic expressions and a symbol that compares them.
An equation is an open sentence that contains the symbol =. An inequality is an open sentence that contains one of the symbols <, >, less than or equal to, greater than or equal to.
Solutions:When you substitute a number for the variable in an open sentence like x + 2 = 5 or 2y>6, the resulting statement is either true or false. If the statement is True, the number is a solution of the equation or a solution of the inequality.
