20 t + 14 = 12 t + 5 + 8 t + 12
12 t = 3
t = 3 / 12
t = ¼

5t + 7/2 = 3t + 5/4 + 2t + 3
5t - 3t - 2t = 5/4 + 3 - 7/2
0t = 5/4 - 12/4 - 14/4 = -21/4

r u sure this is the right problem? i think it's wrong because u can't solve for the "t" since it is a zero when u group them up.. check the problem again..

5t+7/2=3t+5/4+2t+3?\

Take all the terms with t to one side and the other terms to the other side of the equation.

5t - 3t - 2t = 5/4 + 3 - 7/2

It is wrong since the left hand side is 0t and the right hand side is not zero.
