which of the following equations has a solution of -7?

3 answers

In order to determine which equation has a solution of -7, you would need to provide me with a list of equations to evaluate. Please share the equations you'd like me to check, and I can help identify which one has -7 as a solution.

4x - 23 = 5, -3x - = 29, -x + 3 + -4, and 5x + 11 + - 24

Let's evaluate each equation to see if any of them have a solution of \( x = -7 \).

  1. Equation: \( 4x - 23 = 5 \)

    Substitute \( x = -7 \): \[ 4(-7) - 23 = -28 - 23 = -51 \quad (\text{not } 5) \]

  2. Equation: \( -3x = 29 \)

    Substitute \( x = -7 \): \[ -3(-7) = 21 \quad (\text{not } 29) \]

  3. Equation: \( -x + 3 - 4 = 0 \)
    (Assuming you meant \( -x + 3 - 4 = 0 \))

    Simplify: \[ -x - 1 = 0 \implies -x = 1 \implies x = -1 \quad (\text{not } -7) \]

  4. Equation: \( 5x + 11 - 24 = 0 \)

    Simplify: \[ 5x - 13 = 0 \implies 5x = 13 \implies x = \frac{13}{5} = 2.6 \quad (\text{not } -7) \]

None of the equations provided have a solution of \( x = -7 \). If you have more equations or need further assistance, feel free to provide them!
