Solve the following systems of equations:
152x−378y=−74
−378x+152y=−604
x=2,y=1
Question 7 (v) Solve the following pair of linear equations. 152x - 378y = - 74 - 378x + 152y = - 604
Solve the following pair of linear equations.
(i) px + qy = p − q
qx − py = p + q
(ii) ax + by = c
bx + ay = 1 + c
(iii)
ax + by = a2 + b2
(iv) (a − b) x + (a + b) y = a2− 2ab − b2
(a + b) (x + y) = a2 + b2
(v) 152x − 378y = − 74
− 378x + 152y = − 604
