700=-9.5904+22.9582ln(x)

Add 9.5904 to both sides

709.5904 = 22.9582*ln(x)

Divide both sides by 22.9582

709.5904/22.9582 = ln(x)

This means that x = e^{(709.5904/22.9582)}

$${\mathtt{x}} = {{\mathtt{e}}}^{{\frac{{\mathtt{709.590\: \!4}}}{{\mathtt{22.958\: \!2}}}}} \Rightarrow {\mathtt{x}} = {\mathtt{26\,493\,706\,281\,623.85}}$$
