Question

UpStudy AI · Accepted Answer

To simplify the expression $$ 3x - 3y - 9x + 7y $$, follow these steps:

1. **Identify Like Terms:**
   - **Terms with $$ x $$:** $$ 3x $$ and $$ -9x $$
   - **Terms with $$ y $$:** $$ -3y $$ and $$ 7y $$

2. **Combine Like Terms:**
   - **For $$ x $$:**
     $$
     3x - 9x = -6x
     $$
   - **For $$ y $$:**
     $$
     -3y + 7y = 4y
     $$

3. **Write the Simplified Expression:**
   $$
   -6x + 4y
   $$

**Final Answer:**  
$$-6x + 4y$$
$$-6x + 4y$$
