[25.4x+6y,=3xy],[8x+9y,=5xyquad (x+0,y+0)]

4 x + 6y = 3 xy , 8x + 9 y = 5xy ( x ne 0 , y ne 0 )

6x+3y=6xy; 2x+4y=5xy

Solve for x and y : 6x + 3y = 7xy, 3x + 9y = 11 xy (x ne 0 , y ne 0 )

x + y = 5 xy , 3x + 2y = 13 xy ( x ne 0, y ne 0 )

If 4x + 6y = 3 xy and 8x + 9y = 5xy then

If the lines 2x^(2)-5xy+3y^(2)+8x-9y+6=0 and kx-y-5=0 are concurrent, then k=

Add: (i) 3x, 7x (ii) 7y, -9y (iii) 2xy, 5xy, -xy (iv) 3x, 2y (v) 2x^(2), -3x^(2), 7x^(2) (vi) 7xyz, -5xyz, 9xyz, - 8xyz (vii) 6a^(3) , - 4a^(3), 10 a^(3), - 8a^(3) (viii) x^(2) - a^(2), -5x^(2) + 2a^(2), -4x^(2) + 4a^(2)

Solve 6x + 3y = 7xy and 3x + 9y = 11xy.
