One-Step Equations I can show that solving an equation leads to finding the value that makes the equation true.

What is a One-Step Equation? An equation is like a balance scale because it shows that two quantities are equal. What you do to one side of the equation must also be done to the other side to keep it balanced. A one-step equation means you only have to perform 1 mathematical operation to solve it. You can add, subtract, multiply or divide to solve a one- step equation.

How do we solve a one-step equation? To solve an equation, we must get the variable by itself. Use inverse operations. Inverse operations are operations that undo each other. + – – + x ÷ ÷ x

What is the variable? What operation is being performed on the variable? What is the inverse operation? (The one that will undo what is being done to the variable.)

Example: Addition Equation What is the variable? What operation is being performed on the variable? What is the inverse operation? Now, let’s check our answer:

Example: Subtraction Equation What is the variable? What operation is being performed on the variable? What is the inverse operation? Now, let’s check our answer:
