6 + 2/5b = 12<br><br> What does “b” equal?
Elis [28]

Answer:

B = 15

Step-by-step explanation:

<u>Combine multiplied terms into a single fraction</u>

6 + 2b/5 = 12

<u>Subtract 6 from both sides</u>

6 + 2b/5 <em>(-6)</em> = 12 <em>(-6)   </em>= 2b/5 = 6

<u>Multiply all terms by the same value to eliminate fraction denominators</u>

2b/5 <em>( x 5) </em>= 6<em> (x 5)</em>

<em />

<u>Simplify</u>

2b = 30
