Number of students attended the fall play![=1296](https://tex.z-dn.net/?f=%3D1296)
Step-by-step explanation:
Let number of adults![=x](https://tex.z-dn.net/?f=%3Dx)
Number of students![=3\times number\ of\ adults-150=3x-150](https://tex.z-dn.net/?f=%3D3%5Ctimes%20number%5C%20of%5C%20adults-150%3D3x-150)
Given that total number of tickets![=1778](https://tex.z-dn.net/?f=%3D1778)
Number of students+ Number of adults![=1778](https://tex.z-dn.net/?f=%3D1778)
![x+(3x-150)=1778\\4x-150=1778\\4x=1778+150\\4x=1928\\x=\frac{1928}{4}\\x=482](https://tex.z-dn.net/?f=x%2B%283x-150%29%3D1778%5C%5C4x-150%3D1778%5C%5C4x%3D1778%2B150%5C%5C4x%3D1928%5C%5Cx%3D%5Cfrac%7B1928%7D%7B4%7D%5C%5Cx%3D482)
