Ca someone solve 8 = b - 1 + 8b STEP BY STEP PLEASE.
larisa [96]

Answer:

b = 1

Step-by-step explanation:

8 = b - 1 + 8b

<em>combine like terms</em>

8 = 9b - 1

<em>add 1 to both sides of the equation</em>

<em>8 + 1 = 9b - 1 + 1</em>

<em>8 + 1 = 9b</em>

9 = 9b

<em>divide both sides of the equation by 9</em>

9/9 = 9b/9

1 = b
