Solve the following pair of equations 2/root x + 3/root y =2 and 4/root x - 9/root y = -1 srisaji@yahoo.com Share with your friends Share 11 Manbar Singh answered this The given equations are :2x + 3y = 2 .......14x - 9y =-1 .......2Let 1x = u and 1y = vNow from 1 and 2, we get 2u + 3v = 2 .......34u - 9v = -1 .....4Multiply 3 by 3, we get 6u + 9v = 6 ......5adding 4 and 5, we get 10u = 5⇒u = 12put the value of u in 3, we get 1 + 3v = 2⇒v = 13now, 1x = u and 1y = v⇒ 1x = 12 and 1y = 13⇒ x = 2 and y = 3⇒ x = 4 and y = 9so, x = 4; y = 9 is the solution. 34 View Full Answer
