what's to solve? there's just an expression
if 8x+3y>=0 and 2y+5x>=0, then the expression is
-(8x+3y)+(2y+5x) = -3x-y
if 8x+3y<0 and 2y+5x>=0, then the expression is
(8x+3y)+(2y+5x) = 13x+5y
if 8x+3y>=0 and 2y+5x<0, then the expression is
-(8x+3y)-(2y+5x) = -13x-5y
if 8x+3y<0 and 2y+5x<0, then the expression is
(8x+3y)-(2y+5x) = 3x+y
-|8X-3Y|+|2Y+5X|.....SOLVE
