" (a) "[x+3y=6],[2x-3y=2]

Solve x+3y=6,2x-3y=12

4x-2y=3 6x-3y=5

Check graphically whether the pair of equations x+3y=6 " "…(1) and 2x-3y=12" "…(2) is consistent. If so, solve them graphically.

2x+3y=5 6x+9y=10

2x-y=1 ; 6x+3y=5

2x+3y=8 4x-5y=-6

Solve the following simultaneous linear equations by drawing graphs for them : (iv) 3x-2y = 6 , 3x -2y =3

Solve: {:(2x + y = 2),(6x - 3y = 20):}

If 2x^2y\ a n d\ 3x y^2 denote the length and breadth of a rectangle, then its area is (a) 6x y (b) 6x^2y^2 (c) 6x^3y^3 (d) x^3y^3
