Well, if 30% of students are in the play then 100%-30% = 70% of students are not in the play, which is also 140.
So we know:
70%*x=140
70% is also 7/70:
![\frac{7}{10} x=140](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B10%7D%20x%3D140)
divide both sides by 7 and multiply by 10:
x=20*10
x=200
there are 200 students in the school
