Question

Solve the inequality

-6r - 10 < 3r - 8

Answer 1

you want to get all the r's on one side and all the "plain numbers" on the other side of the < sign.

so

-6r - 10 < 3r - 8
+ 6r +6r

-10 < 9r - 8 now move the 8 to the other side:
+8 +8

-2 < 9r now isolate the r (variable)
/9 /9

-2/9 < r

Answer 2

-6r-3r<-8+10
-9r<2
r>-2/9.
since when an equality is divided by a negative sign,,it changes.ok?
