1 answer

To solve the equation \( ax - 9 = 20 \), you can follow these steps:

  1. Add 9 to both sides:

    \[ ax - 9 + 9 = 20 + 9 \]

    This simplifies to:

    \[ ax = 29 \]

  2. Divide both sides by \( a \) (assuming \( a \neq 0 \)):

    \[ x = \frac{29}{a} \]

So, the solution for \( x \) in terms of \( a \) is:

\[ x = \frac{29}{a} \]
