k = 23

To check the answer, substitute k = 23 into the equation:

23 - 9/2 = 23 - 4.5 = 18.5

The left side of the equation equals the right side, so the answer is correct.

Apologies for the mistake. Let's solve it again.

To solve the equation k - 9/2 = 11, we need to isolate the variable k.

First, let's simplify the equation by subtracting 9/2 from both sides:
k - 9/2 + 9/2 = 11 + 9/2
k - (9/2) + (9/2) = 11 + 9/2
k = 11 + 9/2

Next, let's find a common denominator for 11 and 9/2, which is 2:
k = 11(2/2) + 9/2
k = 22/2 + 9/2
k = (22 + 9)/2
k = 31/2

So, the solution to the equation is k = 31/2.

To check the answer, substitute k = 31/2 into the equation:

31/2 - 9/2 = 15.5 - 4.5 = 11

The left side of the equation equals the right side, so the solution is correct.
