Hi

Solve the system of equations then classify the system.

y = -x-11

3x -2y = -18

3x -2(-x-11) = -18

3x + 2x+22 = -18

      5x = -40

       x = -8 and y = -3 (y = -(-8) - 11 = -3)

  Ordered pair(-8,-3) the solution for this Independent system

CHECKING our Answer***

3x -2y = -18

3*-8 + 2*3 = -18



A consistent system has at least one solution.

An inconsistent system has no solutions.

An independent system has exactly one solution.

A dependent system has infinitely many solutions.
