Simplify \(\frac{9}{5}x\) to \(\frac{9x}{5}\).
\[-\frac{9x}{5}=-45\]
Multiply both sides by \(5\).
\[-9x=-45\times 5\]
Simplify \(45\times 5\) to \(225\).
\[-9x=-225\]
Divide both sides by \(-9\).
\[x=\frac{-225}{-9}\]
Two negatives make a positive.
\[x=\frac{225}{9}\]
Simplify \(\frac{225}{9}\) to \(25\).
\[x=25\]
x=25
