How do I solve the problem (13-k) = 11 and k can not equal 2

Step 1. Let's add -11 to both sides of the equation

13-k%2B%28-11%29=11%2B%28-11%29=0 Note 11 cancels out in the right side of the equation.

2-k=0 where 13+(-11)=2

Step 2. Now let's add k to both sides of the equation to get

2-k%2Bk=0%2Bk Note k will cancel out in the left side.

2=k or k=2

Step 3. ANSWER: Based on the above steps, k=2.

Now if 2 is not the answer and if you are at a point to discuss complex numbers then 2i%5E4 where i=sqrt%28-1%29 and i%5E2=-1. This implies i%5E4=1.

I hope the above steps were helpful.
