If 3t – 7 = 5t, then 6t =

Let’s first solve the first equation:

=> 3t – 7 = 5t

=>  3t – 5t = 7

=> -2t = 7

=> t = 7 / -2

=> t = -7/2


If t = -7/2 , then 6t = 6 (-7 / 2)

=> t = -42/2

=>  t = - 21

Thus, the value of t in If 3t – 7 = 5t is -7/2

and the value of t in 6t = is -21

The answer is C.
