Subtract :
`-12 a " from " - 7a `

Answer

To solve the problem of subtracting \(-12a\) from \(-7a\), we can follow these steps:

### Step 1: Write the expression for the subtraction
We start with the expression:
\[ -7a - (-12a) \]

### Step 2: Simplify the expression
Subtracting a negative is the same as adding a positive, so we can rewrite the expression:
\[ -7a + 12a \]

### Step 3: Combine like terms
Now, we combine the terms:
\[ (-7 + 12)a = 5a \]

### Step 4: Determine the sign of the result
Since \(12a\) is greater than \(7a\), the result will be positive. Therefore, we conclude:
\[ 5a \]

### Final Answer
The result of subtracting \(-12a\) from \(-7a\) is:
\[ 5a \]
