Just relax, breathe deeply from the diaphragm, allow the
cleansing air to fill your brain, and take it one step at a time.

You said that                         3t - 7  =  5t

OK.  Fine.
Let's just find out what  6t  is.

Subtract 3t from each side:         -7 = 2t

Multiply each side by  3 :          -21 = 6t

Did I go too fast for you ?
