2x-1/3=7

1 answer

To solve the equation \( 2x - \frac{1}{3} = 7 \), follow these steps:

  1. First, eliminate the fraction by adding \(\frac{1}{3}\) to both sides of the equation:

    \[ 2x - \frac{1}{3} + \frac{1}{3} = 7 + \frac{1}{3} \]

    Simplifying this gives:

    \[ 2x = 7 + \frac{1}{3} \]

  2. To add \(7\) and \(\frac{1}{3}\), convert \(7\) to a fraction with a common denominator:

    \[ 7 = \frac{21}{3} \]

    Now add:

    \[ 2x = \frac{21}{3} + \frac{1}{3} = \frac{22}{3} \]

  3. Now, divide both sides by \(2\) to solve for \(x\):

    \[ x = \frac{22}{3} \div 2 = \frac{22}{3} \cdot \frac{1}{2} = \frac{22}{6} = \frac{11}{3} \]

So, the solution is:

\[ x = \frac{11}{3} \]
