\frac{1}{175}=\frac{1}{300}+x
Divide both sides by 175.
\frac{1}{300}+x=\frac{1}{175}
Swap sides so that all variable terms are on the left hand side.
x=\frac{1}{175}-\frac{1}{300}
Subtract \frac{1}{300} from both sides.
x=\frac{12}{2100}-\frac{7}{2100}
Least common multiple of 175 and 300 is 2100. Convert \frac{1}{175} and \frac{1}{300} to fractions with denominator 2100.
x=\frac{12-7}{2100}
Since \frac{12}{2100} and \frac{7}{2100} have the same denominator, subtract them by subtracting their numerators.
x=\frac{5}{2100}
Subtract 7 from 12 to get 5.
x=\frac{1}{420}
Reduce the fraction \frac{5}{2100} to lowest terms by extracting and canceling out 5.
