Answer:

  d.  t = 30/7

Step-by-step explanation:

You want the solution to the equation 2/3t -1/5t = 2.

Fractions

We can eliminate fractions by multiplying by the least common denominator, 15.

  15(2/3t) -15(1/5t) = 2(15)

  10t -3t = 30 . . . . . carry out the multiplication

  7t = 30 . . . . . . . collect terms

  t = 30/7 . . . . . divide by 7; matches choice D
