$n = 8$

Work Step by Step

$-8n = -64$ We need to isolate the variable $n$ by making it the subject of the formula. This is done by dividing both sides of the equation by $-8$ in order to do away with the negatives on the side of the variable as below: $\frac{-8n}{-8} = \frac{-64}{-8}$ Simplifying the equation, the negatives will cancel out to give: $n = 8$ This shows that the equation has a possible solution at $n = 8$
