Hi

Solving the system of two linear equations by elimination

12x -14y = -8

-8x -14y = 52



12x -14y = -8

8x + 14y = -52   |subtracting 2nd from 1st equation to eliminate y

 20x = -60

      x = -3   

solving for y by substituting x = -3

12x -14y = -8

-36 - 14y = -8

     -28 = 14y

      y = -2



CHECKING our Answer***

 -36 - (-28) = -8   |1st equation

 24 + 28 = 52       |2nd equation
