b = 5

Explanation:

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
