Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Eliminate the fraction in the given equation by multiplying through by 3.
  • Step 2: Solve for x x by isolating it on one side of the equation.
  • Step 3: Compare the result to the provided answer choices and select the correct one.

Now, let's work through each step:

Step 1: Begin with the given equation:
3=(3x1)×13 3 = (3x - 1) \times \frac{1}{3}

To eliminate the fraction, multiply both sides by 3:
3×3=(3x1)×13×3 3 \times 3 = (3x - 1) \times \frac{1}{3} \times 3

This simplifies to:
9=3x1 9 = 3x - 1

Step 2: Solve for x x by isolating it:

Add 1 to both sides to remove the constant term on the right side:
9+1=3x1+1 9 + 1 = 3x - 1 + 1

Thus, we have:
10=3x 10 = 3x

Finally, divide both sides by 3 to isolate x x :
x=103 x = \frac{10}{3}

Step 3: Compare the result to the provided answer choices:

The value x=103 x = \frac{10}{3} is equivalent to the mixed number representation 313 3 \frac{1}{3} .

Therefore, the solution to the problem is 313 3\frac{1}{3} , which matches choice 3.

Answer

313 3\frac{1}{3}
