-11x+13=\frac{1}{5}+\frac{1}{2}
Subtract 1 from 14 to get 13.
-11x+13=\frac{2}{10}+\frac{5}{10}
Least common multiple of 5 and 2 is 10. Convert \frac{1}{5} and \frac{1}{2} to fractions with denominator 10.
-11x+13=\frac{2+5}{10}
Since \frac{2}{10} and \frac{5}{10} have the same denominator, add them by adding their numerators.
-11x+13=\frac{7}{10}
Add 2 and 5 to get 7.
-11x=\frac{7}{10}-13
Subtract 13 from both sides.
-11x=\frac{7}{10}-\frac{130}{10}
Convert 13 to fraction \frac{130}{10}.
-11x=\frac{7-130}{10}
Since \frac{7}{10} and \frac{130}{10} have the same denominator, subtract them by subtracting their numerators.
-11x=-\frac{123}{10}
Subtract 130 from 7 to get -123.
x=\frac{-\frac{123}{10}}{-11}
Divide both sides by -11.
x=\frac{-123}{10\left(-11\right)}
Express \frac{-\frac{123}{10}}{-11} as a single fraction.
x=\frac{-123}{-110}
Multiply 10 and -11 to get -110.
x=\frac{123}{110}
Fraction \frac{-123}{-110} can be simplified to \frac{123}{110} by removing the negative sign from both the numerator and the denominator.
