When posting here in the Weekly Summary section please do not post “answers only” but rather show how you obtained your answers in a step by step manner. If your solution is correct, it is in your best interest for us to see how you obtained the answer. If your solution is incorrect, showing your steps will help us to follow your process and we can then work together to find your mistake. No bonus points will be awarded for answers without explanations.
A maximum of 5 or .25% bonus points will be awarded for 5 correct answers with step by step explanations.
The weekly summary answers and explanations will be posted in the Announcement section by Friday of each week. Please try to work each problem without pasting and copying or you will defeat your purpose of learning. Credit will only be given for “original” work. Please feel free to study the explanations, learn the problem, and create your own step-by-step explanation for bonus points. You may post your explanations throughout the term (please remind your instructor in the General Questions thread to grade your problems if you have posted after Sunday).
NOTE: You may submit a photo of your neat, hand-written work rather than a Word Document.

part3:
-2x + y = 9
6. Solve for (x, y, z), if there is a solution to the given system of linear equations:
– x + 2y + 3z = 0
3x – 2y – 2z = 5
4x + y – 3z = -9
7. Solve: x2 – 4x + 5 = 0.
8, Add the complex numbers: (5 – 2i) + (1 + 6i)
9. Subtract the complex numbers: (4+3i) – (6+i).
10. Multiply the complex numbers (4+3i) (6+i)
