(xy) का मान ज्ञात कीजिए, यदि (i) 3x + 4y = 11, 4x + 3y = 10 (ii) 3x + 2y = 8, 2x + 3y = 7...

Find the values of (x-y) , if (i) 3x + 4y = 11 , 4x + 3y = 10 (ii) 3x + 2y = 8 , 2x + 3y = 7

Find the values of (x+y ) , if (i) 3x + 4y = 11 , 4x + 3y = 10 (ii) 5x - 2y = 4 , x + 8y = 26

If 4x - 3y = 7xy and 3x + 2y = 18xy , then (x,y) =

2x + y = (7xy) / (3), x + 3y = (11xy) / (3)

Solve for x and y , 8x + 5y - 11 = 0 3x - 4y - 10 = 0

I. (x+3)(y+2) = 12 II. 2xy + 4x + 5y = 11

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
