Sorry, that's not correct. Try again!
b-g=15 and g+b = 6
b+15 = gand g - 6 = b
b+g=6 and g- b = 15
b+g=15 and g-b = 6

Let g = number of girls and b = number of boys.
The two equations are:
b + g = 15 (total students)
g − b = 6 (6 more girls than boys)
Solving: add them → 2g = 21 → g = 10.5.
That gives a non-integer, so the numbers are inconsistent as written (you can't have half a student). Possibly the problem has a typo — e.g. if the total were 16 then g = 11 and b = 5, or if the difference were 5 then g = 10 and b = 5.
