Well, since the first 2.28 is in between the two lines you must find is absolute value.
Absolute value is how many places a number is away from 0.
So the absolute value of 2.28 is 2.28, its just its own number.

Answer:
t = 1
Step-by-step explanation:
16 - 2t = t + 9 + 4t; move numbers and t's
-16 -16 ; subtract 16 from both sides
-2t = 5t -7 ; subtract -5t from both sides
-5t -5t
--------------
-7t = -7 ; divide by -7
t = 1
