9 + 5k = 45 + 2K
the sample shows operation S9 to come up with
5K=36+2k assuming subtract 9 from the 45

sample shows K=12 how did they come up with that?

9 + 5k = 45 + 2K

Subtract 9 from both sides.

5k = 45 - 9 + 2k

Subtract 2k from both sides.

5k - 2k = 36

3k = 36
k = 36/3
k = 12

9 +5k = 45 + 2k
-2k -2k
that cancels out now left with
9 + 3k = 45
-9 -9 (-9 form both sides left with)
5k = 36 then divide both sides by 3 and 3 = what

Thank you!
