Joe: 5a + 4b = 6 (1st)
Dawn: 3a + 6b = 6.3 (2nd)
Multiply 1st equation by 3 and 2nd equation by (-5) to eliminate a
15a + 12b = 18
-15a - 30b = -31.5
------------------------------Add
-18b = - 13.5
b = 0.75
substitute b = 0.75 into 5a + 4b = 6
5a + 4(0.75) = 6
5a + 3 = 6
5a = 3
a = 0.6

Wesley and Brian have total 87 baseball cards.
W + B = 87
Wesley has 30 less than twice as many as Brian
W = 2B - 30 (2nd)
So
W + B = 87
2B - 30 + B = 87
3B = 117
B = 39
W + 39 = 87
W = 48
Answer: Wesley has 48 cards and Brian has 39 cards
Hope they help.
