Solve for x: 2x + 6 = 14.

Explanation:
Solving for the variable by isolating it with inverse operations. Start with 2x + 6 = 14. Subtract 6 from both sides to undo the addition: 2x = 8. Then divide both sides by 2 to undo the multiplication: x = 4. Check by substitution: 2(4) + 6 = 8 + 6 = 14, which matches the right-hand side. This shows the value that makes the equation true. Values like 3, 5, or 6 don’t satisfy the equation because they don’t produce 14 when plugged into 2x + 6.
