adding 4 ... -8 r > 24
dividing by -8 ... r < -3
dividing by -8 ... r < -3
to isolate the variable r, add 4 to both sides of the inequality. divide the right side of the inequality by the coefficient of the left side of the inequality. then, leave the numbers as they are, but flip the sign.
-4 - 8r > 20
-4 + 4 - 8r > 20 + 4
-8r > 24
-8r/-8 > 24/-8
r > -3
r < -3
-4 - 8r > 20
-4 + 4 - 8r > 20 + 4
-8r > 24
-8r/-8 > 24/-8
r > -3
r < -3
