Question

5(3b - 3) - 3(3b - 7) = 12please step by step explanation​

Answer 1

Answer:

Step-by-step explanation:

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:

Step-by-step explanation:

we will multiply

15b - 15 - 9b + 21 = 12

we'll solve the like terms

15b - 9b - 15 + 21 =12

6b - 6 = 12

now,

6b = 12 - 6

6b = 6

b = 6/6

b= 1
