lets get rid of the -19 by adding 19 to both sides; keep in mind that we are trying to uncover the "b"

OpenStudy (amistre64):
37 = 14b − 19
+19 + 19
---------------
56 = 14b + 0
56 = 14b

now that the addons are taken care of; we need to get rid of the sticky part; that 14 is stuck to the "b" by multiplication
to undo multiplication we divide

yup we divide
14 years ago
OpenStudy (amistre64):
divide off the 14 to get to the "b"
56 = 14b
/14 /14
---------
56/14 = 1b
and then we simplify 56/14 to match the an answer option
