Pair of Linear Equations in Two Variables

Question 7:

Solve the following pair of linear equations.

(i) px + qy = pq

qx py = p + q

(ii) ax + by = c

bx + ay = 1 + c

(iii)

ax + by = a2 + b2

(iv) (ab) x + (a + b) y = a2− 2abb2

(a + b) (x + y) = a2 + b2

(v) 152x − 378y = − 74

− 378x + 152y = − 604
