Subtraction Equations

For FREE access to this lesson, select your course from the categories below.

Students learn to solve one-step subtraction equations. For example, to solve z - 3 = 16, add 3 to both sides of the equation, to get z = 19. Next, check the solution by substituting a 19 back into the original equation, to get (19) – 3 = 16, which is a true statement, so the solution checks.
