Storyboard Text

• today we are learning how to simplify algebraic expressions. try to solve the problem on the board
• You can demonstrate how you got the answer on the board!
• –17 – t – (t + 3)
• I have the answer!
• For the simplified expression, I had -20+(2t) or -20-2t
• -20 + (-2t)  or -20-2t
• –17+ (-2t) + (-3)
• –17+ (-t)  +  (-t) + (-3)
• –17+ (-t)  + (– (t + 3))
• –17 – t – (t + 3)
• Then, I got rid of the parentheses from t and 3, making them also addition problems with negative signs.
• First, I made all the subtraction problems additions ones with negative signs.
• After that, I grouped the like terms t, and the other set of like terms, which are the -17and -3.
• –17+ (-t)  +  (-t) + (-3)
• –17+ (-t)  + (– (t + 3))
• –17+ (-2t) + (-3)
• –17 – t – (t + 3)
• -20 + (-2t)  or -20-2t
• Thank you for the demonstration!
