The equivalent expression to the given expression is:
[tex]-4.4c+1.1[/tex]
We are given an algebraic equation in terms of the variable c as follows:
[tex]-5.8c+4.2-3.1+1.4c[/tex]
Now, we will first combine the like term i.e. the terms with the same variable term and the constant terms are combined altogether i.e. the expression is given as follows:
[tex]-5.8c+4.2-3.1+1.4c=-5.8c+1.4c+4.2-3.1[/tex]
On simplifying this expression we get :
[tex]-5.8c+4.2-3.1+1.4c=-4.4c+1.1[/tex]
