1 STATION #1: VARIABLES ON BOTH SIDES (BASIC) Copy and solve each equation. Show all work x = 2x z = 84 6z 3. 3 f = 6f (2 + m) = 2(3 m) 5. 4(2y 1) + 5 = 3y Solve the equation: 1 2 h (h 6) = 5 6 h A coffee shop offers a special: 33% extra free or 33% off the regular price. Which offer is a better deal? Explain your reasoning.

2 STATION #2: VARIABLES ON BOTH SIDES (ADVANCED) Copy and solve each equation. Show all work. 1. 4b + 4(1 b) = b (x 1) + 8(x 3) = 6x + 7 5x Follow the instructions for a number puzzle: Take the number formed by the first 3 digits of your phone number and multiply it by 40 Add 1 to the result Multiply by 500 Add the number formed by the last 4 digits of your phone number, and then add it again Subtract 500 Multiply by What is the final number? 2. How does this number puzzle work? 3. Can you invent a new number puzzle that gives a surprising result?

3 STATION #3: FRACTION EQUATIONS Copy and solve each equation. Show all work. 1. 3x = a = = 1 8 x 4. 2x = z = 4 1. Jada s neighbor said, My age is the difference between twice my age in 4 years and twice my age 4 years ago. How old is Jada s neighbor? 2. Another neighbor said, My age is the difference between twice my age in 5 years and and twice my age 5 years ago. How old is this neighbor? 3. A third neighbor had the same claim for 17 years from now and 17 years ago, and a fourth for 21 years. Determine those neighbors ages.

4 STATION #4: EQUATION WORD PROBLEMS (PART 1) Label variables and create and solve equations for each problem. Do not copy the problems. 1. Sally has practiced law three years longer than her younger brother. Together, they have a total of 21 years of practice. How long has her brother practiced law? 2. Juan and Ingrid went selling magazine subscriptions. Ingrid sold four fewer subscriptions than twice as many as Juan sold. Together, they solve 23 subscriptions. How many subscriptions did each sell? 3. A college student is moving into a campus dormitory. The student rents a moving truck for $19.95 plus $0.99 per mile. Before returning the truck, the student fills the tank with gasoline, which costs $ The total cost is $ How many miles did the student drive the truck? 1. Use the distributive property to create an equivalent expression that uses the fewest number of terms: ((((x + 1) 1 ) + 1) 1 ) + 1. If we wrote a new expression following the same pattern so that there 2 2 were 20 sets of parentheses, how could it be expanded into an equivalent expression that uses the fewest number of terms?

5 STATION #5: EQUATION WORD PROBLEMS (PART 2) Label variables and create and solve equations for each problem. Do not copy the problems. 1. A car-rental company charges $22 to customers for the first mile plus an additional $0.75 for every additional mile you drive. If a customer paid $63.75 after using a car for a day, how many miles did they drive? 2. Steve pays $75 in art supplies and plans on selling paintings he has made. If he sells each painting for $15 and wants to make a profit of $405, how many paintings must he sell? 3. Victor spent $20.60 at the carnival. He paid $8 at the entrance and 45 cents for each ride he went on. How many rides did he go on? 1. What is the smallest number that has a remainder of 1, 2, and 3 when divided by 2, 3, and 4, respectively? Are there more numbers that have this property?

6 STATION #6: EQUATION PERIMETER PROBLEMS Label variables and create and solve equations for each problem. Do not copy the problems. 1. The perimeter of a triangular trail is 20 km. The first trail is 1 km shorter than twice the length of the second trail. The third trail is 2 km longer than the first. Find the length of each trail. 2. The perimeter of a rectangular lot is 260 m. The length exceeds the width by 20 m. Find the dimensions of the lot. 3. The side of a square is twice as long as the side of an equilateral triangle. The perimeter of the square is 60 cm more than the perimeter of the triangle. What are the lengths of the sides of the square and the triangle? 1. Han, his sister, his dad, and his grandmother step onto a crowded bus with only 3 open seats for a 42- minute ride. They decide Han s grandmother should sit for the entire ride. Han, his sister, and his dad take turns sitting in the remaining two seats, and Han s dad sits 1.5 times as long as both Han and his sister. How many minutes did each one spend sitting?
