Question

How do you go all the way through with
12b-4 = 12+2(b+1). I dont know where i keel messing up. If i am.

Answer 1

12b - 4 = 12 + 2(b+1)

2 × b = 2b

2 × 1 = 2

12b - 4 = 12 + 2b + 2
+ 4 +4

12b = 12 + 2b + 2 + 4
-2b -2b

10b = 12 + 2 + 4

10b = 18
÷10 ÷ 10

b = 1.8

There you go! I really hope this helped, if there’s anything just let me know! ☻

Answer 2

12b - 4 = 12 + 2(b + 1)

12b - 4 = 12 + 2b +2

12b - 4 = 14 + 2b

      + 4 =+ 4

12b = 18 + 2b

-2b =      -2b

10b = 18

----- = ----

10       10

b = 1.8

answer: 1.8
