Answer:
-4.4c+1.1
Explanation:
You would combine -5.8c and 1.4c or just simply 1.4c-5.8c. This would give you -4.4c as there are no other like terms ending in c. Then you would combine 4.2 and -3.1 which would give you 1.1. Lastly you would put the equation back together which would give you -4.4c+1.1 or 1.1-4.4c
