x=\frac{1}{14}+3-\frac{42}{4}
Divide 6 by 2 to get 3.
x=\frac{1}{14}+\frac{42}{14}-\frac{42}{4}
Convert 3 to fraction \frac{42}{14}.
x=\frac{1+42}{14}-\frac{42}{4}
Since \frac{1}{14} and \frac{42}{14} have the same denominator, add them by adding their numerators.
x=\frac{43}{14}-\frac{42}{4}
Add 1 and 42 to get 43.
x=\frac{43}{14}-\frac{21}{2}
Reduce the fraction \frac{42}{4} to lowest terms by extracting and canceling out 2.
x=\frac{43}{14}-\frac{147}{14}
Least common multiple of 14 and 2 is 14. Convert \frac{43}{14} and \frac{21}{2} to fractions with denominator 14.
x=\frac{43-147}{14}
Since \frac{43}{14} and \frac{147}{14} have the same denominator, subtract them by subtracting their numerators.
x=\frac{-104}{14}
Subtract 147 from 43 to get -104.
x=-\frac{52}{7}
Reduce the fraction \frac{-104}{14} to lowest terms by extracting and canceling out 2.
