Answer:
x = 3
y = -2
Step-by-step explanation:
-6x - 9y = 0 --------------(I)
6x - 5y = 28 ------------(II)
Add equation (I) and (II). Thus x will be eliminated and we can find the value of y.
(I) -6x - 9y = 0
(II) 6x - 5y = 28 {Now add}
-14y = 28
y = 28/(-14)

Plugin y = -2 in equation (I)
-6x - 9*(-2) = 0
-6x + 18 = 0
-6x = -18
x = (-18)/(-6)
[tex]\sf \boxed{\bf x = 3}[/tex]
