online or download it to your computer.
4. Warm - Up: Multi-Step with Distribution
−(−5q+1)=−4(7−8q)
2. −2(4k+1) = −10k − 101. −(−5q+1) = − 4(7−8q)
2(4k+1)=−10k−10
5. Warm-Up Questions
2. 2x - 5 + x - 7 = 8 - 5x + 4 3. 3(2x + 5) = 3(x - 2)
Thursday is the mid point of the 1st quarter. Write a
fraction showing what part of the school year we have
completed.
4. True or False: |-x| = |x| Why or Why Not?
7. What are the steps to solve an absolute value equation?
1. Isolate the Absolute Value | |on one side.
2. Split the Absolute Value into two equations.
3. Solve for the positive exactly the way it is written.
4. Solve for the negative by taking the opposite of the
absolute value.
5. Check your answers by plugging them in!
1. Solve: |x+ 5| = 3 2. Solve: |4x - 1| = 19
3. Solve: 5|x + 3|- 3 = 7
Remember: You always solve 2 equations with
Absolute Value Equations.
