weights as 50-pound weights, for a total of 3180

pounds, how many of each weight are there?

this is howi solved it,

let

$x=$ # of 100 pound weights

$x+6=$ # of 50 pound weights

$3(x+6)=$ # of 20 pound weights

my equation,

$x+x+6+3(x+6)=3180=2x+3x+24=3180=5x+24=3180$ and then $x=631.2$

there are 631.2 (100 pound weights), 637.2(50 pound weeights), and 1911.6 (20 pound weights)

but my answers didn't make sense. because it's not a whole number. i expect to get a whole number.

can you help me with this. thanks.
