How do I solve this equation?

If 3t-7=5t then 6t=

a 21

b-7

c-21

d-42

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.
