To solve the equation \( 3 - \frac{5}{3} x = 18 \), follow these steps: 1. **Isolate the term with \( x \)**: \[ -\frac{5}{3} x = 18 - 3 \] \[ -\frac{5}{3} x = 15 \] 2. **Multiply both sides by \(-1\)** to eliminate the negative sign: \[ \frac{5}{3} x = -15 \] 3. **Multiply both sides by \(\frac{3}{5}\)** to isolate \( x \): \[ x = -15 \cdot \frac{3}{5} \] \[ x = -9 \] So, the solution is: \[ \boxed{-9} \]

To solve the equation \( 3 - \frac{5}{3} x = 18 \), follow these steps:

Isolate the term with \( x \): \[ -\frac{5}{3} x = 18 - 3 \] \[ -\frac{5}{3} x = 15 \]
Multiply both sides by \(-1\) to eliminate the negative sign: \[ \frac{5}{3} x = -15 \]
Multiply both sides by \(\frac{3}{5}\) to isolate \( x \): \[ x = -15 \cdot \frac{3}{5} \] \[ x = -9 \]

So, the solution is: \[ \boxed{-9} \]
