As long as the equation has a solution of 26, it is fine. Let the solution = 26, and let solution = s
You will have to make a equation, in which when you plug in 26 for solution, it is the answer.
let x = a number
For example:
x - 10 = s
s = 26
x -10 (+10) = 26 (+10)
x = 36
x - 10 = 26, in which x = 36
hope this helps
