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
