-4x + y = 6

-5x - y = 21

-4x + y = 6 -5x - y = 21

x + y = 2

-x + 2y = 16

x + y = 2 -x + 2y = 16

-5x + y = -2

-3x + 6y = -12

-5x + y = -2 -3x + 6y = -12

-5x = y - 3

3x - 8y = 24

To determine which system the point (0, -2) is a solution to, we need to substitute x = 0 and y = -2 into each equation of the systems provided and check if the equations hold true.

Let's analyze each system:

  1. System 1:

    • Equation 1: \(-4(0) + (-2) = 6 \rightarrow -2 ≠ 6\) (not true)
    • Equation 2: \(-5(0) - (-2) = 21 \rightarrow 2 ≠ 21\) (not true)

    This system does not include the point.

  2. System 2:

    • Equation 1: \(0 + (-2) = 2 \rightarrow -2 ≠ 2\) (not true)
    • Equation 2: \(-0 + 2(-2) = 16 \rightarrow -4 ≠ 16\) (not true)

    This system does not include the point.

  3. System 3:

    • Equation 1: \(-5(0) + (-2) = -2 \rightarrow -2 = -2\) (true)
    • Equation 2: \(-3(0) + 6(-2) = -12 \rightarrow -12 = -12\) (true)

    This system includes the point.

  4. System 4:

    • Equation 1: \(-5(0) = (-2) - 3 \rightarrow 0 = -5\) (not true)
    • Equation 2: \(3(0) - 8(-2) = 24 \rightarrow 16 = 24\) (not true)

    This system does not include the point.

After checking all the systems, the only system where the point (0, -2) is a solution is System 3: -5x + y = -2 and -3x + 6y = -12.
