It's just a matter of "collecting" all the k terms...

oops, algebra error in my last post...

you just want to multiply everything out, then simplify:

So you just want to multiply everything out and then simplify:

2 (k+5)   -3 (k-1)  = k - 7
2k + 10  -3k +3   = k - 7

Then collect the k terms on the left side and the number terms on the right:
2k + 10  -3k +3   = k - 7
2k - 3k - k = -7 - 10 - 3

then simplify
2k - 3k - k = -7 - 10 - 3
-2k = -20

Then divide both sides by -2:
-2k/(-2) = -20/(-2)

Finally, simplify to solve for k:
-2k/(-2) = -20/(-2)
-2k/(-2) = 10
k = 10

So, @helloxox, that's a pretty detailed solution... please read through the process and let me know if you have questions, 'cause I will be happy to explain further.  Hopefully after reading it, you get the process of step by step simplifying an equation to isolate or "solve for" the variable.

Sometimes seeing an example worked is helpful.... if the asker, like @helloxox, is one of those who just posts "SOLVE!", then I will be sure not to help further...

In an asynchronous situation like this, sometimes an example helps get the conversation started.

It would be better if you would involve the user to participate in the question.

Trust me, I'm not handing out answers repeatedly, but seeing a problem worked, with explanation included, may well help a student who wants to learn.  Someone who is answer-trolling will take it and run... I get that... but I will remember the lack of effort and not reward it twice, and I will be happy to DM other helpers to give them a heads up on the issue.

@sbanuelos, so @hba is talking about you here... make sure you're learning, not just capturing answers from people like me who are trying to help teach.

hba · Answer

I hope @sbanuelos is learning and not in search of answers like other users :) Anyways,@JakeV8 It Would be better if you would solve a sample question for them,which looks quiet similar with explanation.
