solve \( 5 y=45 \)

To solve the equation \( 5y = 45 \), you simply need to isolate \( y \) by dividing both sides by 5. So, \( y = \frac{45}{5} \), which simplifies to \( y = 9 \). There you go, \( y \) is 9! Want to make sure to double-check your solution? You can always substitute \( y = 9 \) back into the original equation. If \( 5 \times 9 \) equals 45, you know you've got it right. It's a fun way to verify your math!
