Answer:

B = 15

Step-by-step explanation:

Combine multiplied terms into a single fraction

6 + 2b/5 = 12

Subtract 6 from both sides

6 + 2b/5 (-6) = 12 (-6)   = 2b/5 = 6

Multiply all terms by the same value to eliminate fraction denominators

2b/5 ( x 5) = 6 (x 5)

Simplify

2b = 30

B=3 hope that helps
