solving `19x+17y =55, 17x+19y =53`, we get: `(a) x = 3, y-2 (b) x = 3, y =-2 (c) x = 2, y = 1 (d)x=5, y=-3 `

If [2x+y,4x,5x-7 4x]=[7 7y-13 y x+6] , then the value of x+y is x=3 , y=1 (b) x=2 , y=3 (c) x=2 , y=4 (d) x=3 , y=3

{:(2x - 3y = 17),(4x + y = 13):}

{:(2x - 3y = 17),(4x + y = 13):}

On solving 2/3x+ 5y=12" and "x+3/2y=6 , we get

Solve: {:(x + y = 17),(x - y = 1):}

on solving 2/x+3/y=3,3/x+6/y=5 we get,

( 1 ) /(x) + (1 ) /( y) = 7 , ( 2)/(x) + ( 3) /( y) = 17 (x ne 0, y ne 0 ) .

Solve for x and y : 4x = 17 - (x - y)/(8) 2y + x = 2 + (5y + 2)/(3)

If the point P(x ,\ y) is equidistant from A(5,\ 1) and B(-1,\ 5) , then (a) 5x=y (b) x=5y (c) 3x=2y (d) 2x=3y

The solution of 2 (y + 3) - x y(dy)/(dx) = 0 with y =-2, when x =1 is :a) (y + 3) = x ^(2) b) x ^(2) (y + 3) = 1 c) x ^(4) (y + 3) = 1 d) x ^(2) ( y +3) ^(2) = e ^(y +2)
