You can put this solution on YOUR website! .
If DC=6x+2y, BC=3x+2y, AB=25, and AD=14, then x=___ and y=_____
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You forgot to notice in the condition that the quadrilateral ABCD is kind of parallelogram (my be rectangle).
Then use he property of a parallelogram to have the opposite sides congruent.
It will give you the equations
6x + 2y = 25,
3x + 2y = 14.
And the solutions x = and y = .
