3k – 5 = 7k + 7

Say you want k on the left side and the answer on the right side so it can look like this (ex. y = 18 or x=7)

To get k on the left side, you need to get rid of 7k on the right side. To do that, subtract 7k from both sides.

3k-7k -5 = 7k-7k + 7

You should end up with this…

-4k – 5 = 7

Next, you want to get rid of the -5…to do that, you must add 5 to both sides.

-4k – 5 + 5 = 7 + 5

You should end up with this…

-4k = 12

Now, you want to get rid of -4 from K, to do that, you must divide -4 from both sides…

-4k/-4 = 12/-4

You should end up with this answer…

k = -3

-12=4k

-3=k

12p = 6 – 3p

15p=6

p=6/15

p=2/5

5/6t + 4 = 2 – 1/6t

6/6t+4=2

t+4=2

t=-2
