`(3y-3)/(y)÷(7y-7)/(3y^(2))` is

(3y-3)/(y) div (7y-7)/(3y^2) is …………… .

Equation (3y+1)/(2)=(7y-5)/(4) is simplified to

(dy)/(dx)=(3y-x+7)/(x-7y-3)

Simplify : (i) (5x - 9y) - (-7x + y) (ii) (x^(2) -x) -(1)/(2)(x - 3 + 3x^(2)) (iii) [7 - 2x + 5y - (x -y)]-(5x + 3y -7) (iv) ((1)/(3)y^(2) - (4)/(7)y + 5) - ((2)/(7)y - (2)/(3)y^(2) + 2) - ((1)/(7)y - 3 + 2y^(2))

Simplify: ((1)/(3)y^(2)-(4)/(7)y+11)-((1)/(7)y-3+2y^(2))-((2)/(7)y-(2)/(3)y^(2)+2)

Find the product of (y+(2)/(7)y^(2)) and (7y-y^(2)) and verify the result for y=3

((1) / (3) y ^ (2) - (4) / (7) y + 5) - ((2) / (7) y- (2) / (3) y ^ (2) +2 ) - ((1) / (7) y-3 + 2y ^ (2))

Solve the following differential equation:- (dy)/(dx) =(3x - 7y + 7)/(3y - 7x - 3)

(3x-7y-3)dy=(3y-7x+7)dx
