Inn quadrilateral ABCD, diagonals AC and BD intersect at point E.
If AE = 4x - 3
and
CE = 17 - x
find x.

i think my answer is toatlllllly worng

I did
well quadrilateral = 360 right.
so i did i dont knwo why it just came in my head maybe i have to do it this way :
4x - 3 = 360 oh no shoudl i do 180 instead of 360 cuz then 180 is half of the quad?
ok anyways...i did

4x - 3 + 17 - x = 360 or mayb 180 i'll check!
4x + 17 - x = 363
4x - x = 346
and this is where i get stuck......
and if i do with 180
it comes out to
4x - x = 160

help me plzzzzzz
i know that this isnt right but i dont know what to do!
 
That makes no sense at all.

AE and CE are LENGTHS?
360 is a DEGREE measure?

Why are those related? Is there more to the problem statement?
 
yeah thats what i said.
doenst make sense.
so can u help me out with the problem
 
Since you've got segments and lengths, it might be better to work with segments and lengths than switching to angles and measures, about which, in this case, you know nothing.

Hint: Try relating the given information on segment lengths to the results you've learned regarding the lengths of diagonals of quadrilaterals and, in particular, how they relate when they intersect.
