The correct answer is:
Multiply each side by 3
The correct first step in solving the equation 1/3x = -9 is to multiply each side by 3.
To solve this equation, we want to isolate the variable x by getting rid of the fraction 1/3.
Here's how you would do it:
1. Start with the equation: 1/3x = -9.
2. Multiply each side of the equation by 3. This cancels out the denominator of 1/3 and simplifies the equation: (1/3) * 3x = -9 * 3.
3. Simplify each side of the equation: (1 * x) = -27.
4. The equation becomes: x = -27.
Therefore, the correct option is to multiply each side by 3.
