let the no of left handed girls be x then no of right handed girls will be 5x
and let no of left handed boys be y then no of right handed boys will be 9x
x+y = 18 equation 1
5x+9y = 122 equation 2
multiplying equation 1 by 5
5x+5y = 90 equation 3
subtracting equation 3 from equation 2
5x - 5x + 9y - 5y = 122 - 90
4y = 32
y = 8
from equation 1
x + y = 18
x + 8 = 18
x = 10
