" s."0.8x-0.5y)(1.5x-3y)

Solve for x and y: 0.4x-1.5y=6.5, 0.3x+0.2y=0.9

0.2x + 0.3y = 1.3,0.4x + 0.5y = 2.3

If 0.5x+0.7y=0.74 and 0.3x+0.5y=0.5 then

The linear system of equations {:(8x-3y-5z=0),(5x-8y+3z=0),(3x+5y-8z=0):}} has

Find the following products: (6x)/5(x^3+y^3) (ii) x y(x^3-y^3) (iii) 0. 1 y(0. 1 x^5+0. 1 y)

Solution of D.E (dy)/(dx)=(2x+5y)/(2y-5x+3) is,if (y(0)=0) (1) x^(2)-y^(2)+5xy-3y=0 (2) x^(2)+y^(2)+5xy-3y=0 (3) x^(2)-y^(2)+5xy+3y=0 (4) x^(2)-y^(2)-5xy-3y=0

Solve for x and y : 0.4 x - 1.5 y = 6.5 , 0.3 x + 0.2 y = 0.9 .

Prove that the following lines are concurrent also find the point of concurrency. 3x-4y+5=0 " ...(1)" 7x-8y+5=0 " ...(2)" " "4x+5y=45 " ...(3)"
