## The ordered pair (p, q) satisfies the simultaneous equations (a + b)x + (b + c)y+ (c + a) = 0 and (b + c) x + (c + a)y + (a + b)

Question

The ordered pair (p, q) satisfies the simultaneous
equations (a + b)x + (b + c)y+ (c + a) = 0 and (b + c)
x + (c + a)y + (a + b) = 0 such that p and
in the ratio 1 : 2, then which of the following is
correct?
(a) a2 + 2ac + 32 = 262 + 3ab + bc
(b) a² + 12 + 2 = ab + bc + ca
(c) a2 + 3ac + 32 = 362 + 3ab + bc
(d) a3 + b3 + 3 = 3abc
