a: $5
b: $2
-------------------
a+b = 56 subtract a on both sides:
b = 56-a
--------------------------
5a + 2b = 208 substitute for b:
5a + 2(56-a) = 208
5a + 112 - 2a = 208
3a = 96
a = 32
He sold 32 $5 tickets and 56-32 = 24 $2 tickets
------------------------------
check:
32(5) + 24(2) = 160 + 48 = 208 Correct
