14 - 5t = 3(2t+1)
Firstly expand to:
14-5t =6t+3
simplifying we get:
14-3 = 6t+5t
11=11t
thus t = 1

14 - 5t = 3(2t + 1)
14 - 5t = 6t + 3
11t - 11 = 0
11 (t - 1) = 0
t = 1

Let try, if t is 2.
14 - 5(2) = 3 (2(2)+1)
14 - 10 = 3 (4 + 1)
14 - 10 = 3 (5)
Then, it will be *4 = 15*.
Is this correct? Ans: Wrong!
Because not the same digit!
Let try, if t is 1.
14 - 5(1) = 3 (2(1)+1)
14 - 5 = 3 (2 + 1)
14 - 5 = 3 (3)
Then, it will be *9 = 9*.
Is this correct? Ans: CORRECT, CORRECT!
Because it is the same digit!

14-5t=6t+3
14-14-5t=6t+3-14
-5t=6t-11
-5t-6t=6t-5t-11
-11t=-11
11t/-11=-11/-11
t=1
