Question

Yuri solved the equation below incorrectly. Explain the step where he went wrong.
(see reply bar for equation)

Answer 1

15b - 1 = 30

Step 1. 15b - 1 - 1 = 30 - 1
Step 2. 15b = 29
Step 3. \[\frac{ 15b }{ 15 } = \frac{ 29 }{ 15 }\]
Step 4. \[B = \frac{ 29 }{ 15 }\]

Answer 2

First off, it should be +1 in step 1. There you go.

Answer 3

\(\large{b=\dfrac{31}{15}}\)
