3. Separate the problem from the answer; draw a line through the equal sign Add, subtract, multiply, or divide the answer and the number we know Make sure you use inverse operations!!!!!! Check your work!!!!!!!

4. Example:

5. Solve. Check your work. 15 + b = 23 V – 15 = -27 M + 4 = -12 -15x = 0 k/11 = 16

6. Solve and check your work. Troy received 73 candy bars from 6 houses. What was the amount of candy Troy received from each house? In 1996, 108 million kids went trick-or-treating on Halloween night across the US. This was42 million kids less than the number of kids that went last year. Write and solve an equation to find out how many kids went trick-or-treating last year. In 1997, 467 thousand bags of candy were sold in October. This was 512 thousand fewer bags sold in 2010. Write and solve an equation to find out how many bags of candy were sold in 2010.

7. Divide your problem by the equal sign Circle the variable Get rid of the number attached to the variable with addition or subtraction Multiply or divide

8. Example

9. Solve and check your work. 2 + 5x = 32 9 + 4x = 41 x/2 + -5 = -5 7x +4 = 4 x/5 – 7 = -9

10. Solve and check your work You buy a fog machine and 3 bags of candy for a Halloween party. The fog machine costs $124 and you spend $154. How much did each bag of candy cost? Tommy has eaten 110 pieces of his 290-piece pile of candy. He eats 20 pieces each day. How many days will it take Tommy to finish his candy? Tom and Jerry use 6 ¾ cups of sugar to make some Twix and Milkyways. They used 1 ½ cups of sugar to make the Twix. Their Milkyway recipe calls for 1 ¾ cups of sugar per bar. How many bars of Milkyways did Tom and Jerry make?
