Answer 6

To solve the equation \( x + 11 = -17 \), you should subtract 11 from both sides of the equation. This will isolate \( x \).

So, the correct response is:

**subtract 11**.

Answer 7

To solve the equation \( x + 23 = 9 \), you need to isolate \( x \). You can do this by subtracting 23 from both sides:

\[
x + 23 - 23 = 9 - 23
\]

This simplifies to:

\[
x = 9 - 23
\]

Calculating the right side gives:

\[
x = -14
\]

So, the solution of the equation \( x + 23 = 9 \) is \( x = -14 \).

Answer 8

The solution to the equation \( x + 23 = 9 \) is \( x = -14 \).

Answer 9

To find which equation has a solution of \( x = -8 \), we can substitute \(-8\) into each equation.

1. **For** \( x + 3 = -11 \):
\[
-8 + 3 = -5 \quad (\text{not } -11)
\]

2. **For** \( x - 10 = 2 \):
\[
-8 - 10 = -18 \quad (\text{not } 2)
\]

3. **For** \( x - 8 = 0 \):
\[
-8 - 8 = -16 \quad (\text{not } 0)
\]

4. **For** \( x - 4 = -12 \):
\[
-8 - 4 = -12 \quad (\text{is } -12)
\]

The equation that has a solution of \( -8 \) is:

**\( x - 4 = -12 \)**.

Answer 10

To solve the equation \( x - 3.41 = -19 \), you should isolate \( x \) by adding \( 3.41 \) to both sides of the equation. This will give you:

\[
x - 3.41 + 3.41 = -19 + 3.41
\]

So the correct response is:

**add 3.41**.

Answer 11

To determine which equation has a solution of \( x = -\frac{1}{2} \), we can substitute \(-\frac{1}{2}\) into each equation.

1. **For** \( x + 1 = \frac{1}{2} \):
\[
-\frac{1}{2} + 1 = \frac{1}{2} \quad \text{(LHS: } \frac{1}{2} \text{, true)}
\]

2. **For** \( x + \frac{1}{2} = -1 \):
\[
-\frac{1}{2} + \frac{1}{2} = -1 \quad \text{(LHS: } 0 \text{, not } -1)
\]

3. **For** \( x - 1 = -\frac{1}{2} \):
\[
-\frac{1}{2} - 1 = -\frac{1}{2} \quad \text{(LHS: } -\frac{3}{2} \text{, not } -\frac{1}{2})
\]

4. **For** \( x - \frac{1}{2} = 1 \):
\[
-\frac{1}{2} - \frac{1}{2} = 1 \quad \text{(LHS: } -1 \text{, not } 1)
\]

The equation that has a solution of \( x = -\frac{1}{2} \) is:

**\( x + 1 = \frac{1}{2} \)**.
