1. Copy the essential question on the top of page 13: How can you explain if a linear equation has one solution, no solution, or infinite solution? Warm-up Solve the situation. Show your work. You are folding origami cranes that will be used as decorations at a wedding. If you make cranes for 1 hour without a break, you can make 40 cranes. During a 3 hour period, you make 100 cranes. How much time did you spend not making cranes? 30 minutes

3. One Solution Solve: 3x – 5 = 13 3x – 5 = 13Write original equation 3x – 5 + 5 = 13 + 5Addition property 3x = 18Simplify Division property Division property X = 6Simplify

4. No solution Solve: -2(x – 5) = 7 – 2x -2(x – 5) = 7 – 2x -2(x – 5) = 7 – 2x -2x + 10 = 7 – 2x -2x + 10 = 7 – 2x -2x + 10 – 7 = 7 – 7 – 2x -2x + 10 – 7 = 7 – 7 – 2x -2x + 3 = -2x -2x + 3 = -2x -2x + 2x + 3 = -2x + 2x -2x + 2x + 3 = -2x + 2x 3 = 0 3 = 0 Write original equationWrite original equation Distributive propertyDistributive property Subtraction propertySubtraction property SimplifySimplify Subtraction propertySubtraction property SimplifySimplify This solution is not true – so there is no solution.

5. Infinite many solutions Solve: 5(3 – 2x) = -(10x – 15) 5(3 – 2x) = -(10x – 15) 5(3 – 2x) = -(10x – 15) 15 – 10x = -10x + 15 15 – 10x = -10x + 15 15 – 10x + 10x = 15 – 10x + 10x 15 – 10x + 10x = 15 – 10x + 10x 15 = 15 15 = 15 Write original equationWrite original equation Distributive propertyDistributive property Addition propertyAddition property SimplifiedSimplified This solution is true – so there is infinite many solutions. Any number you put in for x will work.
