Chapter 3, Problem 30CR

To determine

The solution of the given expression.

Answer to Problem 30CR

  $c<-2$

Explanation of Solution

Given information:

The given expression is:

  $6(c-1)<-18$

Calculation:

The solution can be calculated as:

  $\begin{array}{l}6(c-1)<-18\\ \Rightarrow 6c-6<-18\\ \Rightarrow 6c-6+6<-18+6\\ \Rightarrow 6c<-12\\ \Rightarrow \frac{6c}{6}<\frac{-12}{6}\\ \Rightarrow c<-2\end{array}$

Thus, the solution is $c<-2$ .
