\[ 4x - 1 = 2x + 0.6 \]
\[ 4x - 2x = 0.6 + 1 \]
\[ 2x = 1.6 \]
\[ x = \frac{1.6}{2} \]
\[ x = 0.8 \]
\[ 1 \frac{2}{3} = \frac{5}{3} \]
\[ \frac{5}{6}x + \frac{5}{3} = 2x - 3 \]
\[ 5x + 10 = 12x - 18 \]
\[ 10 + 18 = 12x - 5x \]
\[ 28 = 7x \]
\[ x = \frac{28}{7} \]
\[ x = 4 \]
\[ 3(3x - 2) = 5(2x - 1) \]
\[ 9x - 6 = 10x - 5 \]
\[ -6 + 5 = 10x - 9x \]
\[ -1 = x \]
\[ x = -1 \]
