Question

solve p+q=2,p+q=6 by cross multiplication method​

Answer 1

Answer:

The given equation is

px+qy=p-q .... i

qx-py=p+q .... ii

By cross multiplication method

x/-qp-q-p+pq = y/-pq+q+p+pq = 1/-p²-q²

x/-q²-p² = y/q²+p² = 1/-p²-q²

x/-q²-p² = 1/-p²-q² , y/q²+p² = 1/-p²-q²

x = -p²-q²/-p²-q² , y = p²+q²/-p²-q²

x = 1 and y = -1

Answer 2
