An equation is like a balanced scale. As long as you do the exact same thing to both sides (add, subtract, multiply, or divide), the scale stays balanced. We use this property to reveal the unknown 'x'.
The equation remains true even if you add, subtract, multiply, or divide by the same number on both sides.
When moving a term to the opposite side of the '=' sign, change its sign (+ to -, - to +). This is essentially adding/subtracting the same amount from both sides.
Your ultimate goal is to isolate 'x' on the left side. Remove extra numbers using transposition and division.
