$q = -117$

$-39 = \frac{q}{3}$ We need to isolate the variable $q$ by multiplying through by $3$ as shown below: $-39 \times 3 = \frac{q}{3} \times 3$ Simplifying we have: $-117 = q$ Rearranging the equation we have: $q = - 117$ This implies that the equation has a possible solution at $q = - 117$
