Mind Expander

To solve the equation \( -7y = -91 \), we can start by isolating \( y \). Divide both sides by \( -7 \), which gives us \( y = \frac{-91}{-7} \). Simplifying that, we find \( y = 13 \). You've just found the value of \( y \) that satisfies the equation! Always remember to check your solution by substituting \( y \) back into the original equation. If \( -7(13) = -91 \) holds true, then your solution is correct! This step is a great habit to ensure no mistakes slipped through the cracks.
