I guess the easiest way to show you is by using an example:
1) 5=x-2
Okay, we need to keep both sides of the equal sign EQUAL. To do this, add 2 from 2 (you always add/subract the same value as the number you are adding from,) and evidently you get x. Now, to keep the sides equal, we need to subtract 2 from the 5. The reason we add fom the five and not x is because x is a variable, and 2 is a number... You cannot add from different terms. Anyways, your equation should look something like this:
1) 5=x- 2
+2 +2
_________
7=x
Since all you have is a three and an equal sign left over, your answer is 7 = x, or more properly x = 7. I hope I've helped!

an equation that only requires one operation done to solve it or so i believe
It really depends on the equation; except for the most trivial equations, you will usually need more than one step.

There are different methods of using quadratic functions depending on the equation.
two algebraic steps (not counting simplification steps) must be used to solve the problem. 1st step is adding or subtracting some quantity from both sides of the equation. 2nd step is multiplying or dividing by a number to solve.
