What must be subtracted from -1 to get -6?

Options

A. 5
B. -5
C. 7
D. -7

Answer

To solve the problem "What must be subtracted from -1 to get -6?", we can follow these steps:

### Step 1: Set up the equation
Let the number to be subtracted from -1 be represented by \( x \). According to the problem, we can write the equation as:
\[ -1 - x = -6 \]

### Step 2: Isolate \( x \)
To isolate \( x \), we need to move -1 to the other side of the equation. We can do this by adding 1 to both sides:
\[ -1 - x + 1 = -6 + 1 \]
This simplifies to:
\[ -x = -5 \]

### Step 3: Solve for \( x \)
Now, we need to get \( x \) by itself. To do this, we can multiply both sides of the equation by -1:
\[ x = 5 \]

### Conclusion
Thus, the number that must be subtracted from -1 to get -6 is \( 5 \).
