Which ordered pair is a solution to the system of equations?
enot [183]

Answer:

  • See below

Step-by-step explanation:

<u>Given system:</u>

  • 2x - y = - 2
  • 15x - 2y = - 7

<u>Solve by elimination, multiply the first equation by - 2 and add up the equations:</u>

  • -2(2x - y) + 15x - 2y = - 2(- 2) - 7
  • -4x + 2y + 15x - 2y = 4 - 7
  • 11x = - 3
  • x = - 3/11

<u>Find the value of y:</u>

  • 2( - 3/11) - y = - 2
  • -6/11 - y = - 2
  • y = 2 - 6/11
  • y = 1/11

<u>Solution is:</u>

  • ( - 3/11, 1/11)
  • <em>None of the answer choices is matching this solution. Something must be wrong with the given equations.</em>
