Given the following equation:

x + y + z + 11 = v solve for z:

Start by subtracting x from both sides:

x -x + y + z + 11 = v - x

y + z + 11 = v - x

Subtract y from both sides:
y - y + z + 11 = v - x - y

z + 11 = v - x - y

Subtract 11 from both sides:
z + 11 - 11 = v - x - y - 11

The final answer is:
z = v - x - y - 11
