Hi,

solve using the elimination method

10x + 11y=-26.5

20x + 5y = -27.5



-20x  - 22y= 53      |multiplying thru by -2 to eliminate the x variable

20x + 5y = -27.5

     -17y = 25.5

        y = -1.5     

 20x+5(-1.5) = -27.5 

   20x = -20

     x = -1

CHECKING our Answer***

 -10 + 11(-1.5) = -26.5
