Answer:

5(3b-3)-3(3b-7)=12

8b-15-9b+21=12

-b+6=12

-b=12-6

-b=6

Step-by-step explanation:

substituting the value of b in the equation to check whether 5(3b-3)-3(3b-7) is equal to 12 or not.

5(3×6-3)-3(3×6-7)

5(18-3)-3(18-7)

5(15)-3(11)

45-33=12

so we can conclude that. 5(3b-3)-3(3b-7)=12

12=12
