Since -28 doesn't contain a variable to solve for, move it to the right side of the equation by adding 28 to both sides.
n = 28.

Change the addition to a subtraction sign. 

Like → n - 28 = 0  (The '28' that's behind the negative sign is a negative 28.. By the way)

Then add a positive '28' to both sides.

So, that means 'n=28'
