x+\frac{1}{2}=\frac{4}{7}
Swap sides so that all variable terms are on the left hand side.
x=\frac{4}{7}-\frac{1}{2}
Subtract \frac{1}{2} from both sides.
x=\frac{8}{14}-\frac{7}{14}
Least common multiple of 7 and 2 is 14. Convert \frac{4}{7} and \frac{1}{2} to fractions with denominator 14.
x=\frac{8-7}{14}
Since \frac{8}{14} and \frac{7}{14} have the same denominator, subtract them by subtracting their numerators.
x=\frac{1}{14}
Subtract 7 from 8 to get 1.
