>using 9 with repeats allowed
wat?

make 26,850 by adding 9 of the possible numbers allowing for repeats

not possible, you sure you got the correct numbers?

>>7589518
impossible
here are all possible combinations with sum of them included,

If my linear algebra is okay then:
we got these equations:
6300x + 450y + 3150z + 1350a = 26850
x + y + z + a = 9

Gauss reduction gives that z and a are free variables and
y = 5.10 - 0.54z - 0.85a
x = 3.9 - 0.46z - 0.15z

The decimals here are all rounded, they gave long streams of decimals in my calculator.

if we take z = 1 and a = 1 then
x = 3.29 and y = 3.71
x + y + z + a = 9 indeed but the problem is decimals
In this problem only whole numbers make sense
and only positive numbers make sense

I don't know which of the infinite combinations of Zs and As will give a whole number answer but what is true is that both Z and A can be any positive whole number in the range 1 - 4

make 26,850 by adding 9 of the possible numbers allowing for repeats

Try using 4800 as an extra unit

I've found only one combination so far 4800plus (4)3150 plus 6300 (2)1350 450

>>7589768
6300 + 4800 + 3150 + 3150 + 3150 + 3150 + 1350 + 1350 + 450

>>7589768
also (3)6300 + 4800 + 1350 + (4)450

So is that it only two combinations?

>>7589805
that's two more than you could figure on your own faggot

>>7589816
Actually I was the one that posted the first combination I just have no idea how to find any others since there are other requirements like 3150 and 4800 have to be used at least once
