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 #1*t#, so:
#=6t+13#

Hope this helps.
