Transcript text: $-x-7 x+6 y+8 y$

Solution

Step 1: Identify Like Terms

In the expression $-x - 7x + 6y + 8y$, we need to identify the like terms. Like terms are terms that have the same variable raised to the same power.

The terms $-x$ and $-7x$ are like terms because they both contain the variable $x$.
The terms $6y$ and $8y$ are like terms because they both contain the variable $y$.
