(" 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)

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

(3y-3)/(y)÷(7y-7)/(3y^(2)) is

(1) (5)/(2x)+(2)/(3y)=7,(3)/(x)+(2)/(y)=12

Find (x+y)+(x-y), if x=(5)/(4),y=(-1)/(3) (ii) x=(2)/(7),y=(4)/(3)( iii) x=(1)/(4),y=(3)/(2)

(4y+1)/(3)+(2y-1)/(2)-(3y-7)/(5)=(47)/(10)

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

Find each of the following products: (i) (x + 3) (x - 3) (ii) (2x + 5)(2x - 5) (ii) (8 + x)(8 - x) (iv) (7x + 11y) (7x - 11y) (v) (5x^(2) + (3)/(4) y^(2)) (5x^(2) - (3)/(4) y^(2)) (vi) ((4x)/(5) - (5y)/(3)) ((4x)/(5) + (5y)/(3)) (vii) (x + (1)/(x)) (x - (1)/(x)) (viii) ((1)/(x) + (1)/(y)) ((1)/(x) - (1)/(y)) (ix) (2a + (3)/(b)) (2a - (3)/(b))

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

(1) / (6) (4y + 5) - (2) / (3) (2y + 7) = (3) / (2)
