On solving, we get $c = - 3 .$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenequationis 18 鈭� 27 = 15 c 鈭� 9 c 鈭� 3 c . \\ Wehavetosolvethegivenequation. \end{array}$

Step 2. Simplify

$\begin{array}{l} Now, \\ 鈬� 18 鈭� 27 = 15 c 鈭� 9 c 鈭� 3 c \\ 鈬� 鈭� 9 = (15 鈭� 9 鈭� 3) c [Simplifyeachside] \\ 鈬� 鈭� 9 = 3 c \\ 鈬� 鈭� \frac{9}{3} = \frac{3 c}{3} [Dividebothsidesby3] \\ 鈬� 鈭� 3 = c \\ o r \\ 鈬� c = 鈭� 3 \end{array}$
