#b = -5#

Explanation:

Step 1) Isolate each term containing #b# on one side of the equation and each term not containing #b# on the other side of the equation while keeping the equation balanced:

#-5b - 10 + 5b - 5 = -2b + 5 + 5b - 5#

#-10 - 5 = -2b + 5b#

Step 2) Combine like terms and then solve for #b# while keeping the equation balanced:

#-15 = (-2 + 5)b#

#-15 = 3b#

#-15/3 = (3b)/3#

#-5 = 1b#

#b = -5#
