Here, Susan has x number of marbles and Angel has 2x number of marbles,
          the total is 36,

So,     2x+x = 36     and solving for x gives us x=12

Therefore, Susan has 12 marbles and Angels has 12*2 = 24 marbles.

a + s = 36
a = 2s
so
2s+s=36
3s=36 
s=36:3
s=12 marbles

a = 2s=2*12=24 marbles

Answer
Angel has 24 marbles. Susan has 12 marbles.
