1. Answer:

     4t -5

   Step-by-step explanation:

   You simplify an expression by eliminating parentheses and combining like terms.

   Simplify

     8t+1+(−4t)+(−6)

   First, we eliminate parentheses. A product involving an odd number of minus signs is negative.

     8t +1 -4t -6

   It may be helpful to group variable terms and constant terms.

     (8t -4t) +(1 -6)

   The coefficients of like terms are added:

     (4t) +(-5)

   Expressed without the parentheses, the simplified expression is …

     4t -5
