Answer
$b = 7$
Work Step by Step
We begin by combining like terms together to obtain the equation:
$13 = 3b - 8$
We now need to isolate the variable $b$ by adding $8$ to both sides as shown below:
$13 + 8 = 3b - 8 + 8$
Simplifying, we have:
$21 = 3b$
We now divide through by the coefficient of the variable as shown below:
$\frac{21}{3} = \frac{3}{3}b$
Simplifying we have:
$7 = b$
Rearranging it, we have:
$b = 7$
This shows that the equation has a possible solution at the point $b = 7$
