5x+y=13 5x+5y = 12

5x + y = 135x + 5y = 12

1 + 5x + 3y = 9 2x 3y = 12 X = (x, y) - 4

3 x + 5y = 12, 5x + 3y = 4 .

Factorise : 3 - 5x + 5y - 12(x-y)^(2)

Solve the following system of equations: x+y=5x y ,\ \ \ \ 3x+2y=13 x y ,\ \ \ x!=0,\ \ \ y!=0

Find the equation of a straight line through the intersection of lines 7x+3y=10, 5x-4y=1 and parallel to the lines 13x+5y+12=0 .

{:(3x + 5y = 12),(3x - 5y = - 18):}

Solve by cross-multiplication method. (i) 8x-3y=12,5x=2y +7 (ii) 6x+ 7y -11 =0, 5x+ 2y =13 (iii) (2)/(x)+(3)/(y) =5, (3)/(x) -(1)/(y) +9=0

3 x + 2y = 12 , 5x - 2y = 4 .
