The question is, can you help me solve problems like:
5 - 2n = 8n -(-4n) ?© BrainMass Inc. brainmass.com March 4, 2021, 6:16 pm ad1c9bdddf
In problems like the one you sent me, you basically just want to put all the terms with a variable on one side of the equation, and put all the terms without a variable on the other side. That's the first part of doing these problems. So if we do that to your problem, we get this:
5 - 2n = 8n - (-4n) First, cancel the two negatives.
5 - 2n = 8n + 4n Now you add the two things on the right together
5 - 2n = 12n Now we want to get all the terms that have
an "n" in ...
This solution explains in a step-by-step process how to solve the problem: 5 - 2n = 8n -(-4n).
