Question

Simplify the expression 2-(4-t) when t = 1

Answer 1

2-4+t=-2+t

Answer 2

so if t = 1
-2+1 = -1
therefore -1

Answer 3

2-(4-t)

Replace t for 1.

2-(4-1). Now you have to remember the order of operations. The first step is to figure out whats in the parenthesis. 4-1. 4-1=3.

Now we have 2-(3). That is your simplified equation. As Mathmetics said, the answer is -1.
