#b=-7#

Explanation:

Step 1: Subtract 8b from both sides.

#10b+18−color(blue)(8b)=8b+4−color(blue)(8b)#

#2b+18=4#

Step 2: Subtract 18 from both sides.

#2b+18−color(green)(18)=4−color(green)(18)#

#2b=−14#

Step 3: Divide both sides by 2.

#(cancel2b)/cancelcolor(orange)(2)=(−14)/color(orange)(2)#

#b=−7#
