[12x+y=14],[x-y=4]

x + y = 14x-y = 4

x + y = 14x-y = 4

x+y=14 and x-y=4

Classify the following pairs of lines as coincident, parallel, perpendicular or intersecting : (i) 6x+14y-16=0 , 12x+28y-32=0 (ii) 3x-4y=8 , 3x+4y=11 (iii) 5x-2y=7 , 2y-5x=-7 (iv) 4x+7y=19 , 7x-4y=-2 (v) x-2y=7 , 4y-2x=13

Solve for x and y - 4/x+3y=14 3/x-4y=23

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

3x+2y=14; x+4y=7

If 8x^2 + y^2 -12x -4xy+9 =0 , then the value of (14x-5y) is:
