I think of a positive number, add one, multiply my answer by itself, take away twice the number I first thought of, and my answer is 26. What number did I think of?
The answer is 5.
My Solution:
x = unknown number...
According your clue, form one equation.
(x+1)(x+1) - 2x = 26
If you simplify this equation, you will get a result 5. :)
