Solve `99x + 101 y = 499 ; 101x + 99y = 501`

Solve 99x+101y=499;101x+99y=501

101 103 99 105 97 ? 95

Solve the simultaneous equations: 49x + 51y = 499, 51x+ 49y = 501

Solve the following system of equations: 99x+101y=499,quad 101x+99y=501

101xx99

( 9)/(x) - ( 4)/( y) = 8 , ( 13)/(x) + ( 7)/(y) = 101 ( x ne 0, y ne 0 )

If average of 20 observation x_(1), x_(2), ……x_(20) is y . then the average of x_(1) - 101, x_(2) - 101, x_(3) - 101, ……. X_(20) - 101 is :
