See the entire solution process below:

Explanation:

First, rewrite the inequality as:

$c - 1.4 \ge 2.3$

Now, add $\textcolor{red}{1.4}$ to each side of the inequality to solve for $c$ while keeping the inequality balanced:

$c - 1.4 + \textcolor{red}{1.4} \ge 2.3 + \textcolor{red}{1.4}$

$c - 0 \ge 3.7$

$c \ge 3.7$
