When you substitute z=1 into the equation 3z + (2+I)w = 11-i, it becomes:

3(1) + (2+I)w = 11 - i,
3 + (2+I)w = 11 - i.

Now, let's solve for w:

(2+I)w = 11 - i - 3,
(2+I)w = 8 - i.

Dividing both sides by (2+I):

w = (8 - i) / (2+I).

To simplify, we can multiply the numerator and denominator by the conjugate of the denominator, which is (2-I):

w = (8 - i)(2 - I) / (2+I)(2-I),
w = (16 - 8i - 2i + i^2) / (4 + 1),
w = (16 - 10i - 1) / 5,
w = (15 - 10i) / 5,
w = 3 - 2i.

So, when z=1, the solution for w is 3 - 2i.
