(y-(7-8y))/(9y-(3+4y))=(2)/(3)

(9y+1/(4y))^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))

lim_(y rarr(1)/(2))[(1-8y^(3))/(y-4y^(3))]

3y(9+3)=(8y+3)

Solve: (y-8)/3=(7-4y)/7

Solve: (y-8)/3=(7-4y)/7

(4)/(x)+(3)/(y)=1,(8)/(x)-(9)/(y)=7
