**sophia**, Tuesday, October 16, 2007 at 8:03pmif you add 2t + 1 =3 so 3-1=2 so 2 times what equals 2. not -1 because that would equal negative 2. its 1 because 2 times 1 is 2 plus 1 is three.

**Ms. Sue**, Tuesday, October 16, 2007 at 8:07pmIt's not -1.

2t + 1 = 3

Subtract 1 from each side of the equation:

2t = 2

Divide both sides of the equation by 2.

t = 1

Here's your original post with the answers.

2t+1=3

it one of the following, but which one?

A) 1

B) -1

C) 2

D) -2
