`x-2y= 0 ` और `3 x + 4y -20 = 0 ` रेखाएँ `:`

x- y + 3 = 0, 2x + 3y - 4 = 0 .

4x - 3y + 4 = 0, 4x + 3y - 20 = 0 .

On comparing the ratios of the coefficients, find out whether the pair of equations x – 2y =0 and 3x + 4y -20 =0 is consistent or inconsistent.

If the lines x - 2y - 6 = 0 , 3x + y - 4 =0 and lambda x +4y + lambda^(2) = 0 are concurrent , then

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

{:(4x - 3y + 4 = 0),(4x + 3y - 20 = 0):}

The line 3x + 2y = 6 will divide the quadrilateral formed y the lines x + y = 5, y – 2x = 8, 3y + 2x = 0 & 4y – x = 0 in

x^(2) - 1 = 0, y^(2) + 4y + 3 = 0
