Question

How do you solve this 13c<-169

Answer 1

First, we divide by 13 both sides of the inequality to get c, and since we are dividing by a positive number, then the orientation of the sign stays the same:

`\begin{gathered} (13c<-169)((1)/(13)) \\ \Rightarrow(13c)/(13)<-(169)/(13)=-13 \\ \Rightarrow c<-13 \end{gathered}`

Therefore, x < -13 and the solution set would look like this:

Then, c will take all the values that are less than -13 and will never be equal to -13
