Answer:
b = 1
Step-by-step explanation:
Given
8 = b - 1 + 8b, that is
8 = 9b - 1 ( add 1 to both sides )
9 = 9b ( divide both sides by 9 )
1 = b
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
