To solve the equation \( ax - 12 = 9 \), we first isolate the term involving \( x \). 1. Start by adding 12 to both sides of the equation: \[ ax - 12 + 12 = 9 + 12 \] This simplifies to: \[ ax = 21 \] 2. Next, divide both sides by \( a \) (assuming \( a \neq 0 \)): \[ x = \frac{21}{a} \] Therefore, the solution to the equation \( ax - 12 = 9 \) is \[ x = \frac{21}{a}. \]

Solve \(ax-12=9\).
