Start with the given equation: \(m - 9 = -6\).
To isolate \(m\), use the addition property of equality by adding 9 to both sides of the equation: \(m - 9 + 9 = -6 + 9\).
Simplify both sides: on the left, \(-9 + 9\) cancels out, leaving \(m\); on the right, calculate \(-6 + 9\).
Write the simplified equation: \(m = -6 + 9\).
Perform the addition on the right side to find the value of \(m\).
