(1)/(2)-(1)/(5)=(x)/(3)+(1)/(4)

(x)/(2)-(1)/(5)=(x)/(3)+(1)/(4)

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

(-(1)/(2)-(2)/(3)+(4)/(5)-(1)/(3)+(1)/(5)+(3)/(4))/((1)/(2)+(2)/(3)-(4)/(3)+(1)/(3)-(1)/(5)-(4)/(5)) is simplified to

(x+2)/(3)-(x+1)/(5)=(x-4)/(3)-1

Prove that: (2^((1)/(2))x3^((1)/(3))x4^((1)/(4)))/(10^(-(1)/(5))x5^((3)/(5)))-:(3^((4)/(3))x5^(-(7)/(5)))/(4^(-(3)/(3))x6)=10

3+(x)/(4)=(1)/(2)(4-(x)/(3))-(5)/(6)+(1)/(3)(11-(x)/(2))

(5x)/(3)-(x-2)/(3)=(9)/(4)-(1)/(2)(x-(2x-1)/(3))
