[m]\frac{1}{3}-\frac{1}{2}=\frac{2}{6}-\frac{3}{6}=-\frac{1}{6}[/m]

[m]\frac{2}{3}\cdot (\frac{1}{3}-\frac{1}{2})=\frac{2}{3}\cdot (-\frac{1}{6})=-\frac{1}{9}[/m]


[m]-\frac{1}{9}=4x+10[/m]

[m]-4x=10 +\frac{1}{9}[/m]

[m]-4x=\frac{91}{9}[/m]

[m]x=\frac{91}{9}:(-4)[/m]

[m]x=-\frac{91}{36}[/m]


[m]x=-2\frac{19}{36}[/m]
