z=6.75?

Do you mean

(z/4) - 4 = 11 ?
if so
z/4 = 15
z = 60

or do you mean
(z-4)/4 = 11 ?
if so
z - 4 = 44
z = 48

To solve the equation z - 4 = 11 / 4, we can follow these steps:

Step 1: Add 4 to both sides of the equation to isolate the variable.
z - 4 + 4 = 11/4 + 4
This simplifies to:
z = 11/4 + 16/4
z = 27/4

So, z is equal to 27/4, or in mixed number form, z = 6 3/4.
