Answer: 6t+13

Explanation:

We can only add/subtract terms with the same variable to the same degree. In this expression, t and 5t have the same variable to the same degree while 7 and 6 are both constants, so:
t+7+5t+6
By rearranging:
=t+5t+6+7
Note that t is really 1t, so:
=6t+13

Hope this helps.
