#### Answer

identity

#### Work Step by Step

Using the properties of equality, the solution to the given equation, $
13t-(5-2t)=5(3t-1)
$, is
\begin{array}{l}\require{cancel}
13t-5+2t=5(3t)+5(-1)
\\\\
13t-5+2t=15t-5
\\\\
13t+2t-15t=-5+5
\\\\
0=0
.\end{array}
Since the solution above ended with a TRUE statement, then the given equation is an identity.
