7th grade pre algebra
posted by William .
We need assistance solving
3 + 2(k+1) = 6 + 3k
I know the 2(k+1) has to become 2k + 2
then we have 3 + 2k + 2 = 6 + 3k
then we can subtract 3k from both sides to get
3 +2k + 2  3K = 6
But can I combine the 3+2 on the left
and the 2k  3k to get 1k?
leaving us with 5 1k = 6
1k = 65
1k = 1
k = 1

Thank you! I had figured it out four ways the wrong way. Don't know what I'm doing wrong. Think it may have to do with the MiDAS rule or something but cannot figure it out.

5/6t + 4 = 2  1/6t
Is the best thing to do first in this case to get rid of the fractions? Should I turn them into decimals or multiply both sides by 6? And when I multiply by 6, do I multiply each factor by 6. SO it becomes
5t + 4(6) = 2(6) t
?
Thanks.
