$b = 5$

$3(3-2b)-3(3b-6)=- 48$

Distributive property:

$a(b-c) = ab - ac$

$=> 3\times 3 - 3\times 2b - 3\times 3b + 3\times 6= -48$

Applying BODMAS rule:

$=> 9 -6b- 9b +18 =- 48$

$=> 9 +18 -6b- 9b =- 48$

$=> 27 -15b = -48$

By transposing,

$=> -15b = -48 -27$

$=> -15b = -75$

$=> b = -75/-15$

$=> b = 5$
