`(1)/(3)x+(1)/(4)y=4,(5)/(6)x-(1)/(8)y=4`

Solve the following pair of equations: (x)/(3) + (y)/(4)= 4, (5x)/(6)-(y)/(8)=4

Solve : (1)/(2x)+(1)/(4y)-(1)/(3z)=(1)/(4),(1)/(x)=(1)/(3y),(1)/(x)-(1)/(5y)+(4)/(z)=2 (2)/(15)

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

If (1)/(x)+(1)/(y)=(1)/(4) and (1)/(x)-(1)/(y)=(3)/(4) , then x=

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 2^(x)=4^(y)=8^(z) and (1)/(2x)+(1)/(4y)+(1)/(8z)=4 find the value of x.

If 2^(x)=4^(y)=8^(z) and ((1)/(2x)+(1)/(4y)+(1)/(6z))=(24)/(7) , then find the value of z.
