t-\frac{6}{13}=\frac{5}{13}
Swap sides so that all variable terms are on the left hand side.
t=\frac{5}{13}+\frac{6}{13}
Add \frac{6}{13} to both sides.
t=\frac{5+6}{13}
Since \frac{5}{13} and \frac{6}{13} have the same denominator, add them by adding their numerators.
t=\frac{11}{13}
Add 5 and 6 to get 11.
