solve ax-9=20

Answer 1

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

1. Add 9 to both sides of the equation:

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

   This simplifies to:

   \[ ax = 29 \]

2. To solve for \( x \), divide both sides by \( a \) (assuming \( a \neq 0 \)):

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

So, the solution is:

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

If you have a specific value for \( a \), you can substitute it in to find the numerical value of \( x \).
