5/9 (x-3) = 8/25

1 answer

To solve the equation \( \frac{5}{9} (x - 3) = \frac{8}{25} \), follow these steps:

  1. Eliminate the fraction by multiplying both sides by the least common multiple (LCM) of the denominators. The denominators are 9 and 25, and their LCM is 225. Multiply both sides by 225:

    \[ 225 \cdot \frac{5}{9} (x - 3) = 225 \cdot \frac{8}{25} \]

  2. Calculate each side:

    \[ 225 \cdot \frac{5}{9} = 25 \cdot 5 = 125 \]

    \[ 225 \cdot \frac{8}{25} = 9 \cdot 8 = 72 \]

    So, we have:

    \[ 125(x - 3) = 72 \]

  3. Distribute on the left side:

    \[ 125x - 375 = 72 \]

  4. Add 375 to both sides to isolate the term with \(x\):

    \[ 125x = 72 + 375 \] \[ 125x = 447 \]

  5. Divide both sides by 125 to solve for \(x\):

    \[ x = \frac{447}{125} \]

Thus, the solution to the equation \( \frac{5}{9} (x - 3) = \frac{8}{25} \) is:

\[ x = \frac{447}{125} \]
