z = x + y / 2

solve for y

Assuming that you meant

z=x+(y/2)

Or z-x =y/2
Or 2(z-x)=y

Otherwise it you meant
z=(x+y)/2
Or x+y= 2z
Or y= 2z-x

parenthesis matter.

To solve for y in the equation z = x + y / 2, we can follow these steps:

Step 1: Isolate the term with y by subtracting x from both sides of the equation:
z - x = y / 2

Step 2: Multiply both sides of the equation by 2 to get rid of the fraction:
2 * (z - x) = 2 * (y / 2)
2z - 2x = y

Therefore, the equation y = 2z - 2x represents the solution for y in terms of x and z.
