[x-4y+14=0],[x-4y=14-0],[0-4y=14]

If [[x-y,z],[2x-y,w]]=[[-1,4],[0,5]] then find the value of x+y.

x + y = 14x-y = 4

x + y = 14x-y = 4

x+y=14 and x-y=4

Find the value of (x-y) , if 5x+4y=14,4x+5y=13

If [[x-y,z],[2x-y,omega]] = [[-1,4], [0,5]], find x,y,z,w

Prove that the lies 3x+y-14=0,x-2y=0 nad 3x-8y+4=0 are concurrent.

Solve the system: x+3y-2z=0,2x-y+4z=0,x-11y+14z=0 .

Find the equation of the circle which cuts the three circles x^2+y^2-3x-6y+14=0,x^2+y^2-x-4y+8=0, and x^2+y^2+2x-6y+9=0 orthogonally.
