x + y = 2

-x + 2y = 16

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

-5x = y - 3

3x - 8y = 24

-5x = y - 3 3x - 8y = 24

-4x + y = 6

-5x - y = 21

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

-5x + y = -2

-3x + 6y = -12

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

To determine which system has the point (0, -2) as a solution, we need to substitute \(x = 0\) and \(y = -2\) into each equation of the given systems and see which one holds true.

System 1:

  1. \(x + y = 2\)

    • \(0 + (-2) = 2\)
    • \(-2 \neq 2\) (Not a solution)
  2. \(-x + 2y = 16\)

    • \(-0 + 2(-2) = 16\)
    • \(-4 \neq 16\) (Not a solution)

So, (0, -2) is not a solution to this system.


System 2:

  1. \(-5x = y - 3\)

    • \(-5(0) = -2 - 3\)
    • \(0 = -5\) (Not a solution)
  2. \(3x - 8y = 24\)

    • \(3(0) - 8(-2) = 24\)
    • \(16 \neq 24\) (Not a solution)

So, (0, -2) is not a solution to this system as well.


System 3:

  1. \(-4x + y = 6\)

    • \(-4(0) + (-2) = 6\)
    • \(-2 \neq 6\) (Not a solution)
  2. \(-5x - y = 21\)

    • \(-5(0) - (-2) = 21\)
    • \(2 \neq 21\) (Not a solution)

So, (0, -2) is not a solution to this system either.


System 4:

  1. \(-5x + y = -2\)

    • \(-5(0) + (-2) = -2\)
    • \(-2 = -2\) (True, it is a solution)
  2. \(-3x + 6y = -12\)

    • \(-3(0) + 6(-2) = -12\)
    • \(-12 = -12\) (True, it is a solution)

(0, -2) is a solution to this system.

Therefore, the correct system is: -5x + y = -2, -3x + 6y = -12.
