                                                 3t - 7     =  5t

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

Divide each side by  2 :              - 3.5  =    t

[tex]3t-7=5t \\ \\ -7 = 5t - 3t \\ \\ -7 = 2t \\ \\ - \frac{7}{2} = t \\ \\ t = - \frac{7}{2} \\ \\ [/tex]

The answer is: t = -7/2 or t = -3.5.
