Exhibit graphically the solution set of the linear inequations x+y =4,x+5y>=5,x<=4,y<=3

4x+3y=4,6x+5y=8

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

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

5x+2y=4 7x+3y=5

2x+3y=3 4x+5y=3

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

x + y le 5, 4x + y ge 4, x + 5y ge 5, x le 4, y le 3 .

The general solution of differential equation (x^6y^4+x^2)dy=(1-x^5y^5-x y)dx is (a)In |x|=x y+(x^4y^4)/4+C (b)In |y|=x y+(x^5y^5)/4+C (c)In |y|=x y+(x^5y^5)/2+C (d)In |x|=x y+(x^4y^4)/5+C

Solve for x and y: 4/x+5y=7,3/x+4y=5
