Z= -3
Turn 1/2 z into 2/4 z and then subtract 1/4 z from both sides

Answer:

The value of z=-0.33 if z is in the denominator(below the line)

The value of z=-3 if z is in the numerator(above the line)

Explanation:

The equation is as follows from the information given if z is the in denominator:


1/(2*z)=-3/4+1/(4*z)


0.5/z=-0.75+0.25/z

We can multiply the whole equation with z:


0.5=-0. 75*z+0.25

Add up all the terms with z and simplify:


z=-0.25/0.75=-0.33

The value of z is -0.33

The equation is as follows from the information given if z is the in numerator:


0.5*z=-0.75+0.25*z

Add up all the terms with z and simplify:


z=-0.75/0.25=-3.3
