Need Help Solving FOUR Unknowns

I have THREE problems, with FOUR unknowns in each, is there any way I
can solve them , I assume I may get more than one set of possible
answers, can anyone help?

6s + 6d + 9a + 10p = 20

10s + 9d + 5a + 6p = 30

16s + 15d + 14a + 16p = 50

Do I need to create a Matrix to solve this? This is not a homework
assignment, I am trying to see how certain game figures are rated in a
minature game and I can't make heads or tails of it!

Thanks
