# How do you solve the equation 1.2c=2.6c=4.56?

Jan 28, 2016

Assuming that one of the equal signs should have been a plus sign:
$1.2 c + 2.6 c = 4.56 \rightarrow c = 1.2$
$1.2 c = 2.6 c + 4.56 \rightarrow c = - 3.2 \overline{857142} \ldots$

#### Explanation:

This question is being answered using the two most likely interpretations (since neither the originator nor the re-requester chose to provide a correction).
$\overline{\textcolor{w h i t e}{\text{XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX}}}$

$\textcolor{b l a c k}{1.2 c + 2.6 c = 4.56}$

$3.8 c = 4.56$
$c = \frac{4.56}{3.8} = 1.2$

$\overline{\textcolor{w h i t e}{\text{XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX}}}$

$\textcolor{b l a c k}{1.2 c = 2.6 c + 4.56}$

$- 1.4 c = 4.56$
$c = - \frac{4.56}{1.4} = - 3.2857 \ldots$ (as above assuming my manual arithmetic is okay).
