d=\frac{3}{10}+\frac{2}{5}
Add \frac{2}{5} to both sides.
d=\frac{3}{10}+\frac{4}{10}
Least common multiple of 10 and 5 is 10. Convert \frac{3}{10} and \frac{2}{5} to fractions with denominator 10.
d=\frac{3+4}{10}
Since \frac{3}{10} and \frac{4}{10} have the same denominator, add them by adding their numerators.
d=\frac{7}{10}
Add 3 and 4 to get 7.
