Question
--------------------------------------------------------
3(2t + 5) = 5t + 25

--------------------------------------------------------
Remove the bracket
--------------------------------------------------------
6t + 15 = 5t + 25

--------------------------------------------------------
Take away 5t from both side
--------------------------------------------------------
6t + 15 - 5t = 5t + 25 - 5t
t + 15 =  25 

--------------------------------------------------------
Take away 15 from both side
--------------------------------------------------------
t + 15 - 15 =  25 - 15
t = 10
