Chapter 0.6, Problem 12E

To determine

To solve the equation $4c+23\le -13$

Answer to Problem 12E

  $c\le -9$

Explanation of Solution

Given Information: $4c+23\le -13$

Formula Used : Linear inequality with one variable

Calculation:

Given equation is

  $4c+23\le -13$

To isolate the variable c, subtract 23 from both sides-

  $4c+23-23\le -13-23$

This gives

  $4c\le -36$

To isolate the variable c, divide by 4 both sides-

  $\frac{4}{4}c\le \frac{-36}{4}$

This gives

  $c\le \frac{-36}{4}$

Hence the final answer is,

  $c\le -9$
