1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
2. Wait patiently for a helper to come along.
3. Once someone helps you, say thank you and close the thread with:

   +close
   

4. Feel free to nominate the person for helper of the week in #helper-nominations
5. Do not ping the mods, unless someone is breaking the rules.
6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

[grim stag]

Try to group same terms

Like numbers with same numbers

Try to factorize and develop

[lusty ginkgo]

@midnight atlas add the same terms together, for example:
2a-3a=-a
2b+3a+4b=3a+6b

For the last one you just gotta develop and see if there's anything to factorise at the end, for example:
10x-5y=5(2x-y)
