Not sure about your question, but one possibility is:
4x= -5y+10
-> x = (-5y+10)/4
use this for your second equation 5x= -y-19
5*[(-5y+10)/4] = -y - 19
(-25y+50)/4 = -y - 19
-25y+50 = -4y - 76
-21y = -126
=> y = (-126)/(-21) = 6
Now you now y, can you find x?
You need to solve 4x= -5*(6)+10 OR 5x= -(6)-19
Remember, (6) is the solution for y. I just wrote 6 instead of y.
