Answer
$b = 5\frac{4}{7}$
Work Step by Step
We first combine like terms together to obtain the equation:
$7b - 9 = 30$
We need to isolate the variable $b$, by adding $9$ on both sides of the equation as shown below:
$7b - 9 + 9 = 30 + 9$
Simplifying we have:
$7b = 39$
We now divide through by the coefficient of the variable as shown below:
$\frac{7}{7}b = \frac{39}{7}$
Simplify to get:
$b = 5\frac{4}{7}$
Therefore, the equation has a possible solution at the point $b = 5\frac{4}{7}$
