\frac{2\times 2x}{6}-\frac{x}{6}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 3 and 6 is 6. Multiply \frac{2x}{3} times \frac{2}{2}.
\frac{2\times 2x-x}{6}
Since \frac{2\times 2x}{6} and \frac{x}{6} have the same denominator, subtract them by subtracting their numerators.
\frac{4x-x}{6}
Do the multiplications in 2\times 2x-x.
\frac{3x}{6}
Combine like terms in 4x-x.
\frac{1}{2}x
Divide 3x by 6 to get \frac{1}{2}x.
\frac{\mathrm{d}}{\mathrm{d}x}(\frac{2\times 2x}{6}-\frac{x}{6})
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 3 and 6 is 6. Multiply \frac{2x}{3} times \frac{2}{2}.
\frac{\mathrm{d}}{\mathrm{d}x}(\frac{2\times 2x-x}{6})
Since \frac{2\times 2x}{6} and \frac{x}{6} have the same denominator, subtract them by subtracting their numerators.

\frac{1}{2}x^{1-1}
The derivative of ax^{n} is nax^{n-1}.
\frac{1}{2}x^{0}
Subtract 1 from 1.
\frac{1}{2}\times 1
For any term t except 0, t^{0}=1.
\frac{1}{2}
For any term t, t\times 1=t and 1t=t.
