Let the number of chaperones = x.....then......the number of students = 7x -13

So..the number of chaperones plus the number of students = 107 ....or....

x + 7x - 13 = 107 add 13 to both sides

8x = 120 divide both sides by 8

x = 15 = the number of chaperones ....so......the number of students must have been 107 - 15 = 92
