You add them together.

$(b - 6) - (2 - 5 b) + (b + 4)$ $(b-6)-(2-5b)+(b+4)$

will turn into

$b - 6 - 2 + 5 b + b + 4$ $b - 6 - 2 + 5b + b + 4$

$6 b - 8 + b + 4$ $6b - 8 + b + 4$

that will equal

$7 b - 4$ $7b-4$

How do you combine like terms in (b−6)−(2−5b)+(b+4)(b - 6) - ( 2- 5b ) + ( b + 4)?
