no solution
D.
all real numbers

Answer 1

–3(5 – 15n) = 15(3n – 2)

Expand the left and right side:
(-3)(5) + (-3)(-15n) = (15)(3n) + (15)(-2)

Tag me if more help needed

Answer 2

it is no solution because
3(-15n + 5) = 15(3n - 2) then
-15(3n - 1) = 15(3n - 2)
so you can see that it is no solution because you cannot have 0 = something.
