For History only (z), we have:
![z +15-2+7-2+2=38](https://tex.z-dn.net/?f=z%20%2B15-2%2B7-2%2B2%3D38)
![z +20=38](https://tex.z-dn.net/?f=z%20%2B20%3D38)

![z =-20+38](https://tex.z-dn.net/?f=z%20%3D-20%2B38)
![z =18](https://tex.z-dn.net/?f=z%20%3D18)
Students with one subject is then calculated as:
![1\ subject = x+y+z](https://tex.z-dn.net/?f=1%5C%20subject%20%3D%20x%2By%2Bz)
![1\ subject = 12 + 28 + 18](https://tex.z-dn.net/?f=1%5C%20subject%20%3D%2012%20%2B%2028%20%2B%2018)
![1\ subject = 58](https://tex.z-dn.net/?f=1%5C%20subject%20%3D%2058)
The true statements are;
- fourteen eleventh graders prefer math and eight tenth graders prefer english.
- twenty-three ninth graders and thirty-five twelfth graders prefer math.
