Step-by-Step Solution

To find the value of xx in the given equation, we will perform the following steps:

  • Step 1: Start with the equation given: 3x19=893x - \frac{1}{9} = \frac{8}{9}.
  • Step 2: To eliminate the constant 19-\frac{1}{9} on the left, add 19\frac{1}{9} to both sides:

3x19+19=89+193x - \frac{1}{9} + \frac{1}{9} = \frac{8}{9} + \frac{1}{9}

This simplifies to:

3x=89+193x = \frac{8}{9} + \frac{1}{9}

Combine the fractions on the right side:

89+19=99=1\frac{8}{9} + \frac{1}{9} = \frac{9}{9} = 1

So, now we have:

3x=13x = 1

  • Step 3: Divide both sides by 3 to solve for xx:

x=13x = \frac{1}{3}

Thus, the solution to the equation is:

x=13x = \frac{1}{3}

Answer

13 \frac{1}{3}
