1)m=xy/z-z/x-1
=m=x²y-z-x/x
=mx-x²y+z+x=0
=x(m-xy+z+1)=0
=m-xy+z+1=0
=-xy=_m_z_1
=x=m+z+1/y
2)x-y/x+y=z
=x²-y+xy/x=z  =x²-y+xy-zx=0  =x(x-y+y-z)=0   =x=z
3)theres an error may b the equation is like this
a=√x+x-b
=a²=x+x-b
=2x-b=a²  =2x=a²+b  =x=a²+b/2
4)f=m-mu/t
=ft=m-mu   =ft-m=-mu    =u=m-ft
5)V=π(R²-r²)h
=V/h=πR²-πr²    =V/h+πR²=-πr²    =πR²-v/hπ=r²      =√πR²-V/hπ=r
