Subtract:
`6xy` from `-12xy`

Answer

To solve the problem of subtracting \( 6xy \) from \( -12xy \), we can follow these steps:

### Step 1: Write the expression for subtraction
We need to subtract \( 6xy \) from \( -12xy \). This can be expressed mathematically as:
\[ -12xy - 6xy \]

### Step 2: Combine like terms
Since both terms are like terms (they both contain the variable \( xy \)), we can combine them. We can do this by adding the coefficients of \( -12 \) and \( -6 \):
\[ -12 - 6 = -18 \]
Thus, we have:
\[ -12xy - 6xy = -18xy \]

### Step 3: Write the final answer
The result of subtracting \( 6xy \) from \( -12xy \) is:
\[ -18xy \]

### Final Answer:
\[ -18xy \]
