सिद्ध कीजिए कि निम्न रेखाये संगामी है :
`3x-4y+5=0, 7x-8y+5=0,4x+5y=45`

3x+4y-5=0 x-y+3=0

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

5) 3x-4y=-7;5x-2y=0 find x and y

5x - 4y + 8 = 0 7x + 6y - 9= 0

Show that the lines 3x-4y+5=0,7x-8y+5=0 and 4x+5y=45 are concurrent.

8x+5y-11=0; 3x-4y-10=0

solve for x and y 2x-3y+7=0 3x+4y-5=0

Show that the lines 3x-4y+5=0,7x-8y+5=0 and 4x+5y=45 are concurrent. Also find their point of intersection.

Solve fir x and y: [5x-4y+8=0],[7x+6y-9=0]

Two consecutive sides of a parallelogram are 4x+5y=0a d n7x+2y=0. If the equation of one diagonal is 11 x+7y=9, Equation of other diagonal : (A) 11x + 7y =0 (B) 3x - 5y + 5 = 0 (C) 7x + 11y = 0 (D) 3x + 5y + 5 =0
