\frac{1}{6x}+\frac{2\times 6}{6x}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 6x and x is 6x. Multiply \frac{2}{x} times \frac{6}{6}.
\frac{1+2\times 6}{6x}
Since \frac{1}{6x} and \frac{2\times 6}{6x} have the same denominator, add them by adding their numerators.
\frac{1+12}{6x}
Do the multiplications in 1+2\times 6.
\frac{13}{6x}
Do the calculations in 1+12.
