To evaluate the expression $$ 3ab + 5b - 6 $$ when $$ a = -1 $$ and $$ b = 3 $$, follow these steps:

1. **Substitute the given values into the expression:**

$$
3(-1)(3) + 5(3) - 6
$$

2. **Calculate each term:**

- **First term:** 
     $$
     3(-1)(3) = 3 \times -1 \times 3 = -9
     $$
   
   - **Second term:** 
     $$
     5(3) = 15
     $$
   
   - **Third term:**
     $$
     -6 \text{ (remains unchanged)}
     $$

3. **Combine the calculated terms:**

$$
-9 + 15 - 6
$$

4. **Perform the addition and subtraction:**

$$
-9 + 15 = 6
$$
$$
6 - 6 = 0
$$

**Final Answer:** The value of the expression is **0**.
When $$ a = -1 $$ and $$ b = 3 $$, the value of $$ 3ab + 5b - 6 $$ is **0**.

What is the value of \( 3 a b+5 b-6 \) when \( a=-1 \) and \( b=3 \) ?
