If we take a look at the seccound equation, we can get from x-5y=19 to x=19+5y. So after that we can substitute x=19+5y into the equation 6x+2y=-10 and we would get 6(5y+19)+2y=-10, so if we continue simplifing it we would get 30y+114+2y=-10,

32y+114=-10, 32y=-124, y=-3.875 so x=19+5(-3.875)=19-19.375=0.375. 

 

So our answeres are:

y=-3.875 or 3 and 7/8

x=0.375 or 3/8
