Final answer:
To solve for an in the equation 3ab = c, divide both sides by 3b, yielding a = c / (3b), with the condition that b is not zero.
Step-by-step explanation:
To solve the equation 3ab = c for a, we need to isolate an on one side of the equation. Starting with the original equation:
3ab = c
We divide both sides of the equation by 3b to get:
a = c / (3b)
This is the solution for an in terms of b and c. It's important to note that b cannot be zero, as division by zero is undefined.
