(x)/(22)+(2y)/(3)=-1" tall "x-(y)/(3)=3

Solve for x and y : (x)/(2)+(2y)/(3)=-1 x-(y)/(3)=3

Solve for x and y: (x)/(2) + (2y)/(3)= -1 and x- (y)/(3)= 3

(x) / (2) + (y) / (3) = 1 (x) / (3) + (y) / (2) = 1

Find the sum of following AP: (x-y)/(x+y),(3x-2y)/(x+y),(5x-3y)/(x+y),...... up to 22 terms

If 4x+5y=83 and (3x)/(2y)=(21)/(22), then y-x=?( a) 3( b) 4 (c) 7 (d) 11

Find each of the following products: (i) (x - 4)(x - 4) (ii) (2x - 3y)(2x - 3y) (iii) ((3)/(4) x - (5)/(6) y) ((3)/(4)x - (5)/(6) y) (iv) (x - (3)/(x)) (x - (3)/(x)) (v) ((1)/(3) x^(2) - 9) ((1)/(3) x^(2) - 9) (vi) ((1)/(2) y^(2) - (1)/(3) y) ((1)/(2) y^(2) - (1)/(3) y)

If x+y+z=xyz , prove that: a) (3x-x^(3))/(1-3x^(2))+(3y-y^(3))/(1-3y^(2))+(3z-z^(3))/(1-3z^(2))= (3x-x^(3))/(1-3x^(2)).(3y-y^(3))/(1-3y^(2)).(3z-z^(3))/(1-3z^(2)) b) (x+y)/(1-xy) + (y+z)/(1-yz)+(z+x)/(1-zx)= (x+y)/(1-xy) .(y+z)/(1-yz).(z+x)/(1-zx)
