#### Storyboard Text

• Hey! Today I'm going to teach you how to do Two-Step Equations.
• Although you may not know it, Two-Step Equations are used all the time in real life! Let's use one example: x-(-3)=10.
• It's the end of the first quarter, and the red team scores a three pointer right before the buzzer. They have "X" points.
• The red team scored the three pointer after the buzzer went off. We are checking for further review.
• At this point, the red team has "X" Points and the referee is taking off 3. Under further review, they decide to give the points back.
• Then we use inverse operation and equality property of subtraction.
• To solve it, we first need to change subtraction into addition. We would use the related addition expression to do this.
• Now, we're back to the equation.
• It would look like this:
• Thanks for learning with me!
• x + 3 =
• -3 =
• x =
• x - ( -3 ) = 10
• Now we know the red team started with 7 points!
• 7
• 10
• -3
