**bobpursley**, Sunday, August 30, 2009 at 2:28pmIf L and M add to 180, then

y-2+2x+3=180 simplify that, then use

N+P=180 or

2x-y+x-1=180 simplify that,

Now you have two standard equations. Solve for x and y.

Bob must have been thinking of supplementary angles

take his two equations and set them equal to 90 instead of 180, that is ...

y-2+2x+3=90 and 2x-y+x-1=90

now solve for x and y, (I got x=36, y=17 ,L=15, M=75, N= 55, and P=35)
