3t + 4 = t + 13
transpose t and it would be negative
transpose 4 and it would be negative
3t -t = 13 -4
2t = 9
divide both sides by 2
t = 2/9

3t + 4 = t + 13
2t = 9
t = 9/2 or 4 1/2
Answer: t = 9/2 or 4 1/2
Proof:
3(4 1/2) + 4 = 4 1/2 + 13
13 1/2 + 4 = 17 1/2
17 1/2 = 17 1/2

move the 4 over to the right giving you 3t=t+9 then move the single t term on the right over to the left and that will give you 2t=9 so t equals 9/2 or 4 1/2

3t + 4 = t + 13
3t - t = 13 - 4
2t = 9
t = 9/2
t = 4.5
stupid
All you people who are bad at math should be ashamed of yourselves. Go to night school and pay attention.

3 t - t = 13 - 4
2 t = 9
t = 9 / 2
t = 4 ½
