See the solution process below:

Multiply the term outside the parenthesis by each term within the prenthesis:

$- 4.5 (b - 3) \to (- 4.5 \times b) - (- 4.5 \times 3) \to$ $color(red)(-4.5)(b - 3) -> (color(red)(-4.5) xx b) - (color(red)(-4.5) xx 3) ->$

$- 4.5 b - (- 13.5) \to - 4.5 b + 13.5$ $-4.5b - (-13.5) -> -4.5b + 13.5$

How do you simplify −4.5(b−3)-4.5(b-3)?
