Hello!

Answer:

$\Large \boxed{\sf q=-216}$

Explanation:

→ We want to solve this equation:

$\sf 15 + (q)/(6) = -21$

◼ Subtract 15 from both sides:

$\sf 15 + (q)/(6) -15= -21-15$

◼ Simplify both sides:

$\sf (q)/(6) = -36$

◼ Multiply both sides by 6:

$\sf (q)/(6) * 6= -36 * 6$

◼ Simplify both sides:

$\boxed{\sf q=-216}$

Conclusion:

The solution of the equation 15 + q/9 = -21 is -216.
