**7th grade pre algebra**

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.

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...
