To solve the equation \(-\frac{4}{9}x = -36\), follow these steps:
1. **Eliminate the negative signs**: You can multiply both sides of the equation by -1 to make the equation easier to work with:
\[
\frac{4}{9}x = 36
\]
2. **Isolate \(x\)**: To solve for \(x\), multiply both sides by the reciprocal of \(\frac{4}{9}\), which is \(\frac{9}{4}\):
\[
x = 36 \times \frac{9}{4}
\]
3. **Perform the multiplication**: First, calculate \(36 \times \frac{9}{4}\):
\[
x = \frac{36 \times 9}{4}
\]
Calculate \(36 \times 9 = 324\):
\[
x = \frac{324}{4}
\]
4. **Simplify the fraction**: Divide \(324\) by \(4\):
\[
x = 81
\]
So, the solution is:
\[
\boxed{81}
\]
