$\boxed {x = 6}$

Step-by-step explanation:

Solve for the value of :

0.4x + 0.4 = 0.6x - 0.8

-Take 0.6x and subtract it from 0.4x :

0.4x + 0.4 - 0.6x = 0.6x - 0.6x - 0.8

-0.2x + 0.4 = - 0.8

-Subtract 0.4 to both sides:

-0.2x + 0.4 - 0.4 = - 0.8 - 0.4

-0.2x = -1.2

-Divide both sides by -0.2 :

$\frac{-0.2x}{-0.2} = \frac{-1.2}{-0.2}$

-Expand by multiplying the numerator and the denominator by :

$x = \frac{-12}{-2}$

$\boxed {x = 6}$

So, the value of is .
