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

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

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))

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

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

Simplify :((-3)/(2)x(4)/(5))+((9)/(5)x(-10)/(3))-((1)/(2)x(3)/(4))

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

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

Add: (3x^(2) - (1)/(5)x + (7)/(3)) + ((-1)/(4)x^(2) + (1)/(3)x - (1)/(6)) + (-2x^(2) - (1)/(2)x + 5)

The range of y=(sec^(2)x-|sec x|+4)/(sec^(2)x+|sec x|+4)is(1)[(3)/(5),1)(3)[(2)/(3),1)(4)[(1)/(3),1)
