1/t + 3 + 4 = 2/t +3 Book says this equals 2, but I get -2.75

Original equation:

1/t + 3 + 4 = 2/t +3

1) subtract 1/t + 3 from both sides =

4 = 1/t + 3

2) multiply both sides by t + 3 =

4t + 12 = 1

3) subtract 12 from both side =

4t = -11

4) divide both sides by 4 =

t = -2.75

Again, book says correct answer is 2. What am I doing wrong?
