[stapel]

1. (8 -2i) + (3 + 6i)

2. i( 6 + i) ( 3 - 2i)

These cannot be solved. Please ask your instructor for corrected instructions.

3. 3l2x - 1l = 21

Divide through by 3, and then solve in the usual manner (like they showed in class). If you get stuck, please reply showing all of your work and reasoning.

Thank you!
