To solve the equation \( ax + 3 = 33 \), we first isolate \( ax \) by subtracting 3 from both sides:
\[ ax = 33 - 3 \]
This simplifies to:
\[ ax = 30 \]
Next, we solve for \( x \) by dividing both sides by \( a \):
\[ x = \frac{30}{a} \]
So the solution for \( x \) in terms of \( a \) is:
\[ x = \frac{30}{a} \]
Note that this solution is valid as long as \( a \neq 0 \). If \( a = 0 \), the equation does not have a solution for \( x \).
