Why does a positive number turn negative when flipped to the other side of an equation?

When we move numbers from one side of an equation to another we are actually performing an action to each side of the equation. For example
X + 3 = 7
to get the 3 to the other side we must subtract it from the left side of the equation. What we do to one side we must also do to the other
X + 3 - 3 = 7 - 3
Most people skip writing the above step and go straight to the next notation
X = 7 - 3
the answer of course is
X = 4
