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

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
