1. **State the problem:** Jane is thinking of a number $x$. Two more than seven times her number is the same as sixteen less than nine times her number.
2. **Translate the problem into an equation:** "Two more than seven times her number" means $7x + 2$.
"Sixteen less than nine times her number" means $9x - 16$.
So the equation is:
$$7x + 2 = 9x - 16$$
3. **Solve the equation:**
Subtract $7x$ from both sides:
$$\cancel{7x} + 2 = 9x - 16 - \cancel{7x}$$
which simplifies to:
$$2 = 2x - 16$$
Add 16 to both sides:
$$2 + 16 = 2x - 16 + 16$$
$$18 = 2x$$
Divide both sides by 2:
$$\frac{18}{\cancel{2}} = \frac{2x}{\cancel{2}}$$
$$9 = x$$
4. **Answer:** The value of $x$ is 9.
