Question 1194383

if line segment AB intersects line segment ED in the middle of point C, then

{{{DC=CE}}}

 if {{{DC=6x+x}}} (? confused why +{{{6x}}}, why not just {{{6}}},so you have {{{6+x}}}) 
and {{{CE=2x+1}}}, 

find the value of {{{x }}}

{{{ 6+x=2x+1}}}

{{{ 6-1=2x-x}}}

{{{ 5=x}}}

=>
{{{ x=5}}}
