student tickets ---- x
adult tickets ------- x+100
children tickets ---- 2000 -x - (x+100) = 1900-2x

5(1900-2x) + 10x + 12(x+100) = 19700
9500 - 10x + 10x + 12x + 1200 = 19700
12x = 9000
x = <b>750 student tickets
x+100 = 850 adult tickets
leaving 400 children tickets</b>

check:
5(400) + 10(750) + 12(850) = 19700
