Neil Roach · Answer 1

A. 1 solution

B. The z's end up crossing out so there is no solution

C. Same thing as B, no solution

D. no solution

E. no solution

F. one solution

Alisa Blackburn · Answer 2

B has no solution because the first and third parts can't both be equal to 1/4

C and D also have no solution

E has no solution

A and F both have one solution.
