x=a29
x equals Start Fraction a over 29 End Fraction

x=11a
x equals Start Fraction 11 over a End Fraction

x=−29a
x equals Start Fraction negative 29 over a End Fraction

x=29a

Answer 1

To solve the equation \( ax - 9 = 20 \), let's isolate \( x \):

1. Add 9 to both sides of the equation:
\[
ax - 9 + 9 = 20 + 9
\]
\[
ax = 29
\]

2. Now, divide both sides by \( a \):
\[
x = \frac{29}{a}
\]

Thus, the solution is:
\[
x = \frac{29}{a}
\]

So the correct response is:
**x equals Start Fraction 29 over a End Fraction**.
