I got (-6.28, -0.76). 

Step 1.) Write out the problems
   -2x=8-6y
   -15x=21-6y

Step 2.) Pick a problem and solve for X
   -2x=8-6y =  x=-4-3y

Step 3.) Plug in the x
    (-15)(-4-3y)= 21-6y
    60 + 45y= 21-6y

Step 4.) Solve for y
    y=-0.76

Step 5.) Plug in the y value into one of the equations
    -2x= 8- 6(-0.76)
    -2x= 8 + 4.56
     x= -6.28

Step 6.) Check your answers
    -2(-6.28)=8-6(-0.76)
    12.56=12.56

Step 7.) Write it out
   (-6.28,-0.76)
