Question 1092000


{{{ x+(3x-1)/9-4=(3x+1)/3 }}}......each term on both sides multiply by {{{9}}}

{{{ 9x+9(3x-1)/9-4*9=9(3x+1)/3 }}}...simplify

{{{ 9x+cross(9)(3x-1)/cross(9)-36=cross(9)3(3x+1)/cross(3) }}}

{{{ 9x+(3x-1)-36=3(3x+1) }}}

{{{ 9x+3x-1-36=9x+3 }}}

{{{ cross(9x)+3x-cross(9x)=1+36+3 }}}

{{{ 3x=40 }}}

{{{ x=40/3 }}}
