Solve 2x + 3 = 11 by subtracting 3 from both sides, then dividing both sides by 2: x = 4. Check by substitution: 2 × 4 + 3 = 11. The goal is to preserve equality, rather than move symbols by magic. Write each operation down; if a result looks strange, substitute it into the original equation and ask whether both sides agree.
