You can combine the same numbers with the same variables using the operation sign for each. For example, using your equation, you would combine the 3n and 4n which is 7n. So your equation would be
7n - 2
All you have to do is since it is in the hundredths then i think all u have to do is make it 100 i am prob dumb but really all u have to do is use a calculator
<span>3x + x - 13 + 4 - 6x =12
Combine like terms....
- 2x - 9 =12
Add 9 to both sides....
-2x = 21
Divide both sides by -2 to get x by its self....
x = -21/2</span>
