First, let's solve the first equation:

0.2*(x-7) = 0.8

Distribute the 0.2:

0.2x - 1.4 = 0.8

Add 1.4 to both sides:

0.2x = 2.2

Divide by 0.2:

x = 11

Now, let's solve the second equation:

3*(0.4-x) = 9

Distribute the 3:

1.2 - 3x = 9

Subtract 1.2 from both sides:

-3x = 7.8

Divide by -3:

x = -2.6

So the solutions to the two equations are x = 11 and x = -2.6.
