Answer:
solution: ( 3 , 6 )


Step-by-step explanation:


make y the subject in equation 2:



insert this in equation 1:






solve for y:



CL will always be the same as LD, the CD line is perpendicular to AB where the L is, so, the extreme points of CD will always be in the same distance of L.
180=2x+y
180-y=2x
(180-y)/2=x
