r<4
Step-by-step explanation:
-3 (r-4) >0 step 1: distribute the - 3
-3r+12>0 explain: - 3 times r = -3r, - 3 times - 4 = 12
next, isolate the - 3r by putting 12 on the other side
-3r+12>0 subtract 12 from both sides
-3r>-12 now, divide both sides by - 3 (you have to flip the > because you are dividing by a negative) - 12 divided by - 3 is 4
so you should end up with r<4
