Answer :
We start with the expression
[tex]$$
-6.4m + 4(0.5m - 0.8).
$$[/tex]
Step 1: Distribute the 4
Multiply 4 by each term inside the parentheses:
[tex]$$
4(0.5m) = 2.0m \quad \text{and} \quad 4(-0.8) = -3.2.
$$[/tex]
So, after distribution, the expression becomes
[tex]$$
-6.4m + 2.0m - 3.2.
$$[/tex]
Step 2: Combine Like Terms
Combine the terms with [tex]$m$[/tex]:
[tex]$$
-6.4m + 2.0m = -4.4m.
$$[/tex]
This gives us the simplified expression:
[tex]$$
-4.4m - 3.2.
$$[/tex]
Thus, the simplified right side of the equation is
[tex]$$\boxed{-4.4m - 3.2}.$$[/tex]
