Answer:
D, infinitely many solutions
Step-by-step explanation:
Let's first simplify the left side:
3/4 z - 1/4 z + 1 = 2/4 z + 1
Clearly, once you simplify the left side, it's the exact same as the right side. This is a true equation: 2/4 z + 1 = 2/4 z + 1
For any value that you put in for z, it will always be equal, no matter what.
Thus, the equation has D, infinitely many solutions.
Hope this helps!
