" d) "0.2x-0.3y+0.5y

If 0.5x+0.7y=0.74 and 0.3x+0.5y=0.5 then

Solve the following equations : 0.2x+0.3y=1.3 0.4x+0.5y=2.3

0.2x + 0.3y = 1.3,0.4x + 0.5y = 2.3

[0.2x+0.3y=1.3],[0.4x+0.5y=2.3]

Let (2,3) be the focus of a parabola and x + y = 0 and x-y= 0 be its two tangents. Then equation of its directrix will be (a) 2x - 3y = 0 (b) 3x +4y = 0 (c) x +y = 5 (d) 12x -5y +1 = 0

Solve for x and y: 0.4x-1.5y=6.5, 0.3x+0.2y=0.9

Solve for x and y : 0.4 x - 1.5 y = 6.5 , 0.3 x + 0.2 y = 0.9 .
