Question
Find the missing polynomial. $(9 y-3)+(\quad)=-4 y+7$.
Step 1
We have $9y$ on the left side and $-4y$ on the right side. To make them equal, we subtract $9y$ from both sides of the equation. This gives us $-13y$ on the right side. So, the $y$ term in the parentheses should be $-13y$. Show more…
