3x-4y=-7,5x-2y=0

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

{:(3x + 2y = 4),(2x - 3y = 7):}

Classify the following pairs of lines as coincident, parallel, perpendicular or intersecting : (i) 6x+14y-16=0 , 12x+28y-32=0 (ii) 3x-4y=8 , 3x+4y=11 (iii) 5x-2y=7 , 2y-5x=-7 (iv) 4x+7y=19 , 7x-4y=-2 (v) x-2y=7 , 4y-2x=13

5) 3x-4y=-7;5x-2y=0 find x and y

x+3y = -4 ; 5x-7y=68

5x + 2y = 31 3x + 7y = 36

3x+2y=5 2x-3y=7

3x+2y=5 2x+3y=7

if (3x-2y):(5x-7y)=5:3 then, find x:y.
