2x - y = 0
x + y = -3
adding up equations the result is:
3x = -3
x = -3/3 = -1
y = 2x = 2(-1) = -2
The solution set for the system 2x - y = 0 x + y= -3 is (-1, -2)

(x + 5 < 4)
x < 4 - 5
x < -1;
(x - 3 > -6)
x > -6 + 3
x > -3
The solution for the inequality system (x + 5 < 4) (x - 3 > -6) is {x | -3 < x < -1}
