Option - (D).
Given equation (p+2q)x + (p-3q)y = p - q can be written as
px + 2qx + py - 3qy = p - q
px + py + 2qx - 3qy = p - q
p(x + y) - q(-2x + 3y) = p - q
x + y = 1 ------------ (1)
-2x + 3y = 1 --------------- (2)
On solving (1)*2 and (2) we get
y = 3/5
substitute y = 5/3 in (1) we get
x = 2/5.
Hope this helps!
