i just dont understand it
Answered by oobleck
you can follow the steps Reiny showed you.
Can you solve

3x ≥ 0 ??
If so, then find x, and then let x = r-4 and then find r.

Is the answer r≥-4
Answered by oobleck
nope. If r=5,
-3(5-4) = -3 which is not ≥4
when you multiply an inequality by a negative value, you change the direction of the inequality. So, the correct answer is r≤4
