To solve this equation, we can start by simplifying both sides of the equation.

On the left side, we have 3 mũ x ÷ 3. Since the exponent is not specified, we can assume it is 1. Therefore, 3 mũ x ÷ 3 is equal to 3x ÷ 3.

On the right side, we have 234 ÷ 3, which simplifies to 78.

So, the equation becomes 3x ÷ 3 = 78.

To solve for x, we can multiply both sides of the equation by 3 to get rid of the fraction:

3x ÷ 3 * 3 = 78 * 3

This simplifies to:

3x = 234

Finally, we can divide both sides of the equation by 3 to solve for x:

3x ÷ 3 = 234 ÷ 3

x = 78

Therefore, the solution to the equation is x = 78.
