You can't.

Explanation:

There isn't anything to solve because in solving you're finding the value(s) of an unknown variable, and there aren't any unknown variables here. It's simply an untrue expression, which is saying that #-5.6 = 13#, which it doesn't.

Assumption: The equation should be #-5.6=4/5x+12.2#

#x=-89#

Explanation:

Don't like decimals so lets get rid of them.

Multiply everything by 10

#-56=2x+122#

Subtract 122 from both sides

#-56-122=2x+0#

#-178=2x#

Divide both sides by 2#

#-89=x#
