For every 6 girls on the softball team there are 9 boys on the baseball team if there are 50 students on both teams how many are girls

Let g = number of girls and b = number of boys, then:-

g + b = 50 (1)

and

for every girl there is 1.5 boys so:-

b = 1.5g(2)

Substitute for b in equation (1):-

1.5g + g = 50

2.5g = 50

g = 20
