  1. Do Now 5/29/13 • Take out HW from last night. • Text p. 463, #2-36 evens • Copy HW in your planner. • Text page 470, #8-34 evens • In your notebook, answer the following question. • Sally Sue just received her cable bill from Comcast. The bill for the month is a total of $114.50. Comcast charges $5.00 for each movie ordered “On Demand.” Sally Sue can’t remember how many “On Demand” movies she ordered in the month? If Sally Sue’s normal bill is $89.50, how many “On Demand” movies did she order? • Can you think of an equation to help you solve this question? Use the variable “m” for movies.

  3. Objective • SWBAT solve two-step equations using algebra

  4. Equation Remember this? 2 s + 8 = 20 Left side Right side ‘s’ has to be 6 in order to make the equation balanced. Like a scale, the left side and right side must be the same in order to be balanced!

  5. Equation- Remember this? • mathematical sentence with an equal sign Like a scale, both sides must be EQUAL in order to be balanced.

  6. Section 11.1“Solving Two-Step Equations” How can you get the “unknown” by itself? 3x + 5 = -19 “Undo” operations by using the INVERSE (opposite) operations to both sides of the equation.

  7. Solving Two-Step Equations… Isolate the variable! Get ‘x’ by itself. 3x + 5 = -19 To get the ‘x’ by itself first get rid of “adding 5.” • 5 • 5 Do the opposite. “Subtract 5.” Whatever you do to one side of the equation you must do the other side. 3x = -24 To get the ‘x’ by itself get rid of “multiplying by 3.” 3 3 Do the opposite. “Divide by 3.” x = -8

  8. Check Your Work! 3x + 5 = -19 x = -8 3(-8) + 5 = -19 Are both sides equal?
