Question

What is the solution....??  b-9+6b=30??

Answer 1

b - 9 + 6b = 30 :First, combine like terms

7b - 9 = 30 :Then, add the 9 over to the other side

7b = 39 :Then, divide the whole equation by 7

b = 5.57

Your final answer:

b = 5.57
or
b = 39/7

Answer 2

`b-9+6b=30 \\\\ 7b=30+9 \\\\ 7b=39 \\\\ \boxed{b=(39)/(7)}`
