It looks like C since it was the start on the other side.
3 times 10^4-5 is 6782 and I really need point so I’m just putting random stuff 45 -67
To get rid of the 3, you multiply the x/3 by 3 to get x by itself. But if you multiply one side you have to multiply the other. So x = 99
Distribute -10
-10n - 50 = 40
Add 50 to both sides
-50 + 50 would cancel
- 50 + 40 = -10
Divide by -10
-10/-10 = 1
N=1
