Question

Combine like terms.

6xy-2y+x+y-99

Answer 1

To combine like terms in the expression \(6xy - 2y + x + y - 99\), we group the terms based on their types:

1. **Terms with \(xy\)**: \(6xy\)
2. **Terms with \(y\)**: \(-2y + y = -2y + 1y = -1y\)
3. **Terms with \(x\)**: \(x\)
4. **Constant term**: \(-99\)

Now we can rewrite the expression by combining these results:

\[
6xy + x - y - 99
\]

So, the final simplified expression is:

\[
6xy + x - y - 99
\]
