To simplify the expression, we can distribute the negative sign on the second part of the expression:
(7x - 2) - (0.04x - 3 + 0.2x)
= 7x - 2 - 0.04x + 3 - 0.2x
Now, let's combine like terms:
= (7x - 0.04x - 0.2x) + (-2 + 3)
= 6.76x + 1
Therefore, 7x - 2) - (0.04x - 3 + 0.2x) simplifies to 6.76x + 1.
