Interpret the statement as the inequality -3x > 18.
Solve:
-3x > 18
Divide both sides by -3 (remember: dividing by a negative flips the inequality):
x < -6
So the solution is x < -6 (interval notation: (-∞, -6)). Example check: x = -7 gives -3(-7) = 21 > 18 (true); x = -6 gives -3(-6) = 18 (not > 18).
