x + 3 = −11
x plus 3 equals negative 11

x − 10 = 2
x minus 10 equals 2

x − 4 = −12
x minus 4 equals negative 12

x − 8 = 0

Answer 1

To determine which of the equations has a solution of \( x = -8 \), we will substitute \(-8\) into each equation and see if the equation holds true.

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

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

3. For the equation \( x - 4 = -12 \): \[ -8 - 4 = -12 \quad (\text{this is true}) \]

4. For the equation \( x - 8 = 0 \): \[ -8 - 8 = -16 \quad (\text{not } 0) \]

The equation that has a solution of \( x = -8 \) is: \( x - 4 = -12 \).
