2.2 Solving Two-Step Equations I can solve two-step equations in one variable.
What is a two-step equation? Requires 2 steps to solve. ◦Involves 2 operations Uses properties of equality and inverse operations to solve. ◦Isolate the variable. Ex:
How to Solve Identify operations Use inverse operations to “undo” them Undo operations in reverse order Ex: 2x+3 = 15 ◦Multiplication and addition Undo ◦Subtract 3: 2x = 12 ◦Divide by 2: x = 6 Solution: x = 6
