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)

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

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

0.5 = - 0.75 + 0.25/z

We can multiply the whole equation with z:

0.5 = - 0.75 + 0.25/z

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 in the numerator:

0.05 . z = - 0.75 +  0.25 . z

Add up all the terms with z and simplify:

z = - 0.75/ 0.25 = -3.3.
