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.
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 \( x = -14 \).
The solution to the equation \( x + 23 = 9 \) is \( x = -14 \).
To find which equation has a solution of \( x = -8 \), we can substitute \(-8\) into each equation.
For \( x + 3 = -11 \): \[ -8 + 3 = -5 \quad (\text{not } -11) \]
For \( x - 10 = 2 \): \[ -8 - 10 = -18 \quad (\text{not } 2) \]
For \( x - 8 = 0 \): \[ -8 - 8 = -16 \quad (\text{not } 0) \]
For \( x - 4 = -12 \): \[ -8 - 4 = -12 \quad (\text{is } -12) \]
The equation that has a solution of \( -8 \) is:
\( x - 4 = -12 \).
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.
To determine which equation has a solution of \( x = -\frac{1}{2} \), we can substitute \(-\frac{1}{2}\) into each equation.
For \( x + 1 = \frac{1}{2} \): \[ -\frac{1}{2} + 1 = \frac{1}{2} \quad \text{(LHS: } \frac{1}{2} \text{, true)} \]
For \( x + \frac{1}{2} = -1 \): \[ -\frac{1}{2} + \frac{1}{2} = -1 \quad \text{(LHS: } 0 \text{, not } -1) \]
For \( x - 1 = -\frac{1}{2} \): \[ -\frac{1}{2} - 1 = -\frac{1}{2} \quad \text{(LHS: } -\frac{3}{2} \text{, not } -\frac{1}{2}) \]
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:
\( x + 1 = \frac{1}{2} \).
