Hi

Solve the system of equations.  Will use Elimination in this case

Note: -2x+2y=2 is the same as 2y-2x = 2

 2y-2x =2     |multiplying thru by -1 to  eliminate the x variable

-4y-2x=-22



 -2y+2x = -2     |result of multiplying thru by -1 to  eliminate the x variable

 -4y-2x  =-22

   -6y = -24

     y = 4 and x = 3   (8 = 2x+2, 6 = 2x and x=3)

CHECKING our Answer***Using -4y-2x=-22

  -8 -6 = -22
