Here, it is convenient to factor out 10^-19. If you like, a calculator or spreadsheet can figure this for you.
Let x equal the number of adult tickets sold.
X + 3X=512
(I put 3x because we know the students sold 3 times as many).

X+3X=512
4X=512
4X/4=512/4
X=128

FG + GH = FGH
FG + 31 = 49
FG = 49-31
FG = 18
Hence the measure of FG is 18
