    check
half perimeter = 6 x + 4 y
is that
4 x - 2 y + 4 x + 2 y
no
=======================
now
6 x + 4 y = 4 x - 2y + a x + b y
6 x = 4 x + a x
a = 2
4 y = - 2 y + b y
b = 6
so I get 2 x + 6 y
================
check mine
6 x + 4 y = 4 x - 2 y + 2 x + 6 y ?????
6 x + 4 y = 6 x + 4 y ..........sure enough
