Answer:


\boxed {x = 6}

Explanation:

Solve for the value of
x:


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:


(-0.2x)/(-0.2) = (-1.2)/(-0.2)

-Expand by multiplying the numerator and the denominator by
10:


x = (-12)/(-2)


\boxed {x = 6}

So, the value of
x is
6.
