Answer 1

3/4z-1/4z+1=2/4z+1
Combine like terms to get
1/2z+1=1/2z+1
Subtract one from both sides to get
1/2z=1/2z
Multiply both sides by 2 to get
z=z. 
This is D, has infinitely many solutions because any number you enter as z will equal itself.
 Ex. 5 as z would be 5=5 which is true with any number.
