Answer
$r = 6$
Work Step by Step
We are given the equation:
$64=8(r+2)$
We begin by opening up the brackets on the right hand side of the equation as shown below:
$64 = 8r + 16$
Next, we isolate the variable $r$ by subtracting $16$ from both sides of the equation as shown below:
$64 - 16 = 8r + 16 - 16$
Simplify to get:
$48 = 8r$
We then divide through by the coefficient of the variable $r$ as shown below:
$\frac{48}{8} = \frac{8}{8}r$
Simplifying the equation, we have:
$6 = r$
Rearranging it, we have:
$r = 6$
Therefore, the equation has a possible solution at the point $r = 6$
