Clear fractions by multiplying both sides of an equation by the least common multiple of all the denominators. 6 Complete lessons: Recall that when evaluating expressions, it is a good practice to first replace all variables with parentheses, and then substitute the appropriate values. We show all the solutions to the inequality \(x>3\) on the number line by shading in all the numbers to the right of three, to show that all numbers greater than three are solutions. The following are some examples of linear inequalities, all of which are solved in this section: A solution to a linear inequality139 is a real number that will produce a true statement when substituted for the variable. pW7&59oEZ`@Q?G8AkCF3CcTKEY*H8A?PKd Solve each equation or inequality.
