Question 1013121
{{{WX+XY=WY}}}, segment addition postulate


{{{3x-1+XY=10x-26}}}, substitution


Also WX=XY  because of X being the midpoint.  You can find the value for x.
{{{3x-1+(3x-1)=10x-26}}}, again by substitution.


{{{6x-2=10x-26}}}
{{{-4x-2=-26}}}
{{{-4x=-24}}}
{{{highlight(x=6)}}}-------------Now you can use this to evaluate XY.
