In One Variable Writing and solving one-step linear equations in one variable sounds quite ominous. However, as we analyze what this means, you will see that it is a skill your students can acquire comfortably.
Equations are statements which say that two quantities are equal.
Solving an algebraic equation is like solving a mystery. You are seeking the value of the variable that will make the equation a true statement. Notice that the variable x in the equation is only raised to the first power. When the variable in an equation is raised to the first power, the equation is linear. When the variable in an equation is raised to a power greater than one, the equation is not linear.
