1/2x-1/y=-11/x+1/2y=8Find value of x and y |
| Answer» Let 1/x = a and 1/y = beqn 1/2x-1/y=-1 is now a/2 - b = -1 or a - 2b = -2 ----------(1)eqn 1/x+1/2y=8 is now a + b/2 = 8 or 2a + b = 16 ---------(2)solving (1) and (2) we get , a= 6. but a = 1/x . Therefore x= 1/6similarly b = 4 . But b = 1/y. Therefore y = 1/4 | |
