Arthur weighs 34 lb more than lily. their combined weight is 180 lbs less than four times lily's weight. how much does arthur weigh?

X = Lilys weight
x + 34 = Arthurs weight
4x - 180 = combined weight

x + x + 34 = 4x = 180
2x + 34 = 4x - 180
-2x           -2x

        34 = 2x -180
     +180        + 180

       214 = 2x
        107  = x  which is Lily's weight
         141 = x + 34 which is Arthur's weight
The total weight is 248

which is the answer that you get when you do 4(107) = 180 or
428 -180 = 248

The right answer should be 6 but your not very specific
