$(2+3 \times 6 - 8 - 9 \div 2 +(3 \color{#D61F06}{+(-9)})\div11 \times 11) \times 10 \div 5\\ =(2+3 \times 6 - 8 - 9 \div 2 + \color{#D61F06}{(3-9)}\div11 \times 11) \times 10 \div 5\\ =(2+\color{#D61F06}{3 \times 6} - 8 - \color{#D61F06}{9 \div 2} + \color{#D61F06}{(-6)\div11 \times 11}) \times 10 \div 5\\ =\color{#D61F06}{(2+18-8-4.5-6)} \times 10 \div 5\\ =\color{#D61F06}{1.5 \times 10 \div 5}\\ =\boxed{3}$

Why dont you become an artist, you use your colours properly :P? Nice solution!
