Step 4: b equals one

Answer 1

ya i got u

Answer 2

ok in step 1 is where he messed up

Answer 3

Before he divides by 15b he has to isolate that variable so you have to subtract 1 from both sides first and u get 15b=29

Answer 4

So he did the first step wrong.

Answer 5

He was suppose to isolate the variable first which means he had to get 15b by itself first before divideing by 15 so he had to subtract 1 first
