Simplify this solution Bonus Knowledge
To solve for \( y \), you need to isolate it on one side of the equation. Start by adding 2 to both sides of the equation: \[ y - 2 + 2 = -9 + 2 \] This simplifies to: \[ y = -7 \] So the solution is \( y = -7 \). If you're ever unsure, just remember that you can always check your work! Substitute \( y \) back into the original equation: \[ -7 - 2 = -9 \] Since both sides equal -9, you can confidently say your solution \( y = -7 \) is correct!
