To solve x+y=3; 3x-2y=4 by determinant method, find D .

solve the inequation 2x - y ge3 by graphical method.

Solve : 3x+ 2y = 14 - x+ 4y = 7

Solve: 2/x+2/(3y)=1/6 and 3/x+2/y=0 and hence find ' a ' for which y=a x-4 .

Solve 2x+3y=11 and 2x-4y=-24 and hence find the value of 'm' for which y=mx+3 .

Solve the folowing sysytem of equation using the method of elimnation by substitution x + y = 7 and 3x - 2y = 11.

Solve 2x+3y=11 and 2x 4y= 24 and hence find the value of 'm' for which y=m x+3 .

Solving 1.5x+0.1y=6.2 and 3x-0.4y=11.2 by substitution method.

Solve: (x^3-3x y^2)dx=(y^3-3x^2y)dydot

Solve 3x - 4y = 20 and x + 2y = 5.

Find the value of x , y 2x+3y=6 3x-2y=4 .
