2x+3y+8=0,x-y-1=0

If the system of equations 2x-3y+4=0,5x-2y-1=0 and 21x-8y+lambda=0 are consistent,then lambda is

find x and y : 2x+3y-8=0, 3x+y-5=0

The equation of the parabola with focus (0,0) and directrix x+y=4 is a. x^2+y^2-2x y+8x+8y-16=0 b. x^2+y^2+8x+8y-16=0 c. x^2+y^2-2x y+8x+8y=0 d. x^2-y^2+8x+8y-16=0

Find the value of a for which the lines 2x+y-1=0 2x+y-1=0 a x+3y-3=0 3x+2y-2=0 are concurrent.

Show that the following equations are consistent. 2x+3y+1=0,x+2y+1=0,x+y=0

Solve for x and y - 2x+3y-8=0 3x+4y-5=0

2x + 3y = 8 , x - 2y + 3 = 0

Show that the lines 2x + 3y - 8 = 0 , x - 5y + 9 = 0 and 3x + 4y - 11 = 0 are concurrent.

Show that the lines 2x + 3y - 8 = 0 , x - 5y + 9 = 0 and 3x + 4y - 11 = 0 are concurrent.

Show that the lines 2x + 3y - 8 = 0 , x - 5y + 9 = 0 and 3x + 4y - 11 = 0 are concurrent.
