Do Now 5/29/13 TTTTake out HW from last night. TTTText p. 463, #2-36 evens CCCCopy HW in your planner. TTTText page 470, #8-34 evens IIIIn your notebook, answer the following question. SSSSally 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? CCCCan you think of an equation to help you solve this question? Use the variable “m” for movies.

Objective SWBAT solve two-step equations using algebra

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

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

6
Section 11.1 “Solving Two-Step Equations” How can you get the “unknown” by itself? How can you get the “unknown” by itself? “Undo” operations by using the INVERSE (opposite) operations to both sides of the equation. Solving Two-Step Equations STEP 1- “Undo” addition and/or subtraction. STEP 2- “Undo” multiplication and/or division. STEP 3- Solve for the variable. STEP 4- Check your work. 3x + 5 = -19

7
Solving Two-Step Equations… 3x + 5 = -19 - 5- 5- 5- 5 -5-5-5-5 3x = -24 3x = -24 Isolate the variable! Get ‘x’ by itself. To get the ‘x’ by itself first get rid of “adding 5.” Do the opposite. “Subtract 5.” Whatever you do to one side of the equation you must do the other side. 33 x = -8 x = -8 To get the ‘x’ by itself get rid of “multiplying by 3.” Do the opposite. “Divide by 3.”

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