Question

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

please step by step explanation​

Answer 1

Answer:

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

15b - 15 - 9b + 21 = 12

15b + 9b + 15 + 21 = 12

24b + 36 = 12

24b = 12 - 36

24b = - 24

b = -24/24

b = 1

Answer 2

Answer:

$\Huge\boxed{B=1}$

Step-by-step explanation:

$\Large\boxed{\mathsf{SUBJECT: MATH}}$

To solve this problem, first, you have to isolate b on one side of the equation. Isolate it on one side of the equation.

DISTRIBUTIVE PROPERTY:

A(B+C)=AB+AC

A(B-C)=AB-AC

5(3b-3)-3(3b-7)=6b+6

6b+6=12

6b+6-6=12-6 (Subtract 6 from both sides.)

12-6 (Solve.)

12-6=6

6b=6

6b/6=6/6 (Then, divide by 6 from both sides.)

6/6 (Solve.)

6/6=1

$\rightarrow \Large\boxed{B=1}$

In conclusion, the final answer is b=1.
