3 times a number x, subtracted from 18, is less than −90.

-Write an inequality for the statement above
-Find the solution set of the inequality
(write the solution using a fraction or integer)

Respuesta :

18-3*x<-90

subtract 18 from both sides to get -3x<-108

divide by -3 to get x>36. We changed the inequality because we divided or multiplied by a negative number
18-3x <-90
X>36
Remember when you divide by a negative number in an inequality, the alligator decides to switch meals, making the sign switch.
