Question:

When you do the inverse operation on both sides we call that equation

Answers

So, you are trying to solve for something, and the only way to do that is through applying the inverse of the given operation. This is because you are trying to "undo" everything and get your variable alone.

For example, if you have x+2=4, the only way to get x alone is to subtract 2, but you need to do this to both sides because you want the same equation as when you started. You are just trying to shift everything away from your variable

then the equation will be  x+2-2=4-2 which means x=2
plug it back in to check, 2+2=4, this is correct so you know you have done it right.'

however, if you hadnt done this to both sides watch what happens

x+2-2=4 which means x=4, now check your answer

you would get 4+2=4 which means 6=4 and you know that is not true

You can do anything you want to one side of an equation.
You'll usually apply an inverse operation to make the side
simpler, for example to get rid of the 'x', or to get rid of the
fractions on that side.

But when you do something to one side of the equation,
you MUST do exactly the same thing to the other side too.
If you don't, then you have changed the equation to a
different one, and the solution to the one you have now
is not the solution to the original one.

Very simple example:

Solve the equation            2x = 2

Correct solution:
Divide each side by  2 :      x = 1

Incorrect solution:
Divide the left side by  2 :    x = 2

You do this to isolate the x value
