Answer:
(21 + 11)2 = 64
So, I don't think teachers do this, but this is my way of doing it
Okay, so first, I divided 64 by 2 :
64 ÷ 2 = 32
Then, I subtracted 11 from 32:
21
Now, to check, just do the problem :
(21 + 11)2 = 64
32 * 2 = 64
Word | know | Unknown
Language| 12 | x

Use cross multiply:
12(28980) = 180(x)
347760 = 180x
347760/180=1932
