Quick Facts

Lesson: 24: Equations, Inequalities and Line Graphs
Topic: Linear Equations in One Variable
Domain: Algebra

An equation is a balance, so whatever you do to one side you must do to the other. Undo the operations in reverse order, and finish only when x stands alone.

Study Tip

Whatever you do must reach the whole side, not just the term with the x in it. Always check by substituting your answer back into the original equation.
