Answer

To begin solving the problem, we start with the equation:

rac{x}{x + 2 imes 81} = 15

We can cross-multiply:

x=15(x+162)x = 15(x + 162)

Expanding this gives:

x=15x+2430x = 15x + 2430

Rearranging leads to:

−14x=2430-14x = 2430

Thus, solving for xx:

x = - rac{2430}{14}

Step 2

For a complete process to find $x$,

Answer

Considering the complete process, we follow through with the following from the derived equations:

x = rac{580}{3}

This provides the final expression for xx.
