Answer:

#b=1#.

Explanation:

  1. Move #2# to the other side of the equation using subtraction.

#8(b-7)+2color(red)- color(red)2=-46color(red)- color(red)2#
#8(b-7)=-48#

  1. Divide both sides by #8# to continue to isolate #b#.

#(8(b-7)) \/8=-48 \/8#
#b-7=-6#

  1. Move #7# to the other side of the equation using addition.

#b-7 color(red)+ color(red)7=-6 color(red)+color(red)7#
#b=-1#
