Answer:
r ≤ -8 is your answer.
Explanation:
Isolate the variable (r). What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 3 from both sides
-2r + 3 (-3) ≥ 19 (-3)
-2r ≥ 19 - 3
-2r ≥ 16
Isolate the variable r. Note that when dividing by a negative number, you must flip the sign.
(-2r)/-2 ≥ (16)/-2
r ≥ 16/(-2)
r ≤ -8
r ≤ -8 is your answer.
