The correct solution is \( x = \frac{21}{a} \), but none of the given options match this answer.
Solución
We start with the given equation:
\[
a x - 3 = 18
\]
**Step 1.** Add \(3\) to both sides of the equation:
\[
a x - 3 + 3 = 18 + 3 \quad \Longrightarrow \quad a x = 21
\]
**Step 2.** Divide both sides by \(a\) (assuming \(a \neq 0\)) to solve for \(x\):
\[
x = \frac{21}{a}
\]
None of the provided answer choices match the result \(x=\frac{21}{a}\).

To solve the equation \( a x - 3 = 18 \), first, add 3 to both sides to get \( a x = 21 \). Next, divide both sides by \( a \) to isolate \( x \), which gives us \( x = \frac{21}{a} \). Looks like none of the options correctly represent this solution; however, the closest choice to our result is option D, which is \( x = \frac{15}{a} \) - but that’s not quite right! Keep practicing those algebra skills; you’re almost there! Do remember that checking your answers is crucial! Misreading or skipping the simplification steps can lead to wrong answers. Always take a moment to verify if your calculated result fits the original equation before concluding. Happy solving!
