Answer:

Assuming that one of the equal signs should have been a plus sign:
#1.2c+2.6c=4.56 rarr c=1.2#
#1.2c=2.6c+4.56 rarr c=-3.2bar(857142)...#

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).
#bar(color(white)("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"))#

#color(black)(1.2c+2.6c=4.56)#

#3.8c = 4.56#
#c=4.56/3.8=1.2#

#bar(color(white)("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"))#

#color(black)(1.2c=2.6c+4.56)#

#-1.4c=4.56#
#c=-4.56/1.4=-3.2857...# (as above assuming my manual arithmetic is okay).
