Answer:
D.
Step-by-step explanation:
A.
9 (x - 3) = 9x - 27 ➡ 0 = 0 (this has infinite solutions)
B.
9x - 3 = 9x - 3 ➡ 0 = 0 (has infinite solutions)
C.
9x - 3 = 27x - 3 ➡ x = 0 (has one solution)
D.
9 (x + 3) = 9(x + 10) ➡9x +27 = 9x +90➡ 9x -9x = 90 - 27 ➡ 0 = 63 (doesn't make sense so it has no solution)
