(13b-2)-3(4b+4)=-3
(13b-2)+(-3(4b+4))=-3
(13b-2)+(-12b-12)=-3
13b-2-12b-12=-3
13b-12b-2-12=-3
1b-14=-3
b=11
(13*11)-3(4*11+4)=
141-3(48)=
141-144=-3

(13b - 2) - 3(4b + 4) = -3 ... Distribute the 3 ...
13b - 2 - 12b - 12 = -3 ... Combine like terms ...
b - 14 = -3 ... Add 14 to both sides ...
b = 11
