Question 676738


 if {{{B}}} is between {{{A}}} and {{{C}}},than 

{{{AC=AB+BC}}}


if {{{AB=3x+2x}}}...for  some reason, I  believe you have {{{AB=3x+2}}} here , {{{BC=35-x}}}, {{{AC=73}}}, than


{{{73=(3x+2)+(35-x)}}}


{{{73=3x+2+35-x}}}

{{{73-35-2=2x}}}

{{{36=2x}}}

{{{36/2=x}}}

{{{18=x}}}


so, {{{AB=3x+2=3*18+2=56}}} and {{{BC=35-x=35-18=17}}}

check

{{{73=56+17}}}

{{{73=73}}}
