-4.

-3k+10=k+2.... First we have to move the K to one side

-3k+10=k+2

__________ This will reduce -3k to -2k and k+2 to just 2

K

-2k+10=2 Now we have to subtract 10 to both sides as to get k alone.

-2k+10=2

________ Now we should have -2k on one side and 2-10 on the other.

-10

-2k=2-10....... 2-10= 8. We have to get -2k into just K on itself so we divide by 2.

-2k=-8

______ Your answer is 4. You have to do one side what you do the other.
