Step-by-step explanation:
The value of seven is in the thousands place and is 10 time the number seven if it were at the hundreds place, which is where 2 is.
7000=10 x 700
7000=7000
For this case we have the following expression:
414x - 812y - 414x
Rewriting we have:
414x - 414x - 812y
We group similar terms:
(414x - 414x) - 812y
Adding we have:
0 - 812y
- 812y
