Let's denote the total number of games played in the first part of the season as \( x \) and the number of games played in the remaining part of the season as \( y \). According to the problem, the team played a total of 119.9999999999999 games, which we can round to 120 for practical purposes. Therefore, we have:

\( x + y = 120 \)  (1)

The team won 40% of the first \( x \) games and 80% of the remaining \( y \) games. The total win percentage is 70%. We can express this as:

\( 0.40x + 0.80y = 0.70 \times 120 \)  (2)

Simplifying equation (2), we get:

\( 0.40x + 0.80y = 84 \)  (3)

Now we have a system of two equations with two variables:

\( x + y = 120 \)  (1)
\( 0.40x + 0.80y = 84 \)  (3)

We can solve this system by multiplying equation (1) by 0.40 to make the coefficients of \( x \) in both equations the same:

\( 0.40x + 0.40y = 0.40 \times 120 \)
\( 0.40x + 0.40y = 48 \)  (4)

Now we subtract equation (4) from equation (3):

\( (0.40x + 0.80y) - (0.40x + 0.40y) = 84 - 48 \)
\( 0.40y = 36 \)

Divide both sides by 0.40 to find \( y \):

\( y = 36 / 0.40 \)
\( y = 90 \)

Now that we know \( y \), we can find \( x \) by substituting \( y \) into equation (1):

\( x + 90 = 120 \)
\( x = 120 - 90 \)
\( x = 30 \)

So, the team played 30 games in the first part of the season.
