i think the answer is -1
is that correct?
if 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.
It'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.

subtract one from each side, then divide each side by 2.
