Which of the following equations has a solution of -8?

x - 10 = 2

x + 3 = -11

x - 4 = -12

x - 8 = 0

1 answer

To determine which of the equations has a solution of -8, we can substitute -8 for \( x \) in each equation and check if it satisfies the equation.

  1. Equation: \( x - 10 = 2 \) \[ -8 - 10 = -18 \quad (\text{not equal to } 2) \]

  2. Equation: \( x + 3 = -11 \) \[ -8 + 3 = -5 \quad (\text{not equal to } -11) \]

  3. Equation: \( x - 4 = -12 \) \[ -8 - 4 = -12 \quad (\text{equal to } -12) \]

  4. Equation: \( x - 8 = 0 \) \[ -8 - 8 = -16 \quad (\text{not equal to } 0) \]

The only equation that has a solution of -8 is: \[ x - 4 = -12 \]
