Answer:

16

Step-by-step explanation:

First, substitute the values of the variables into the expression:

3(y + 4) - (x - 1)

3(2 + 4) - (3 - 1)

Now, simplify both parentheses:

3(6) - 2

tiny-mole [99]

Answer: The team won 100 games and losses 28 games

Step-by-step explanation:

Let the number of games won denoted by x and the games lost is denoted by y .

Given : A minor league baseball team plays 128 games in a season.

Team won 16 more than three times as many games as they lost.

Then, the system of equations, we have

x+y=128-------(1)\\\\x=3y+16------------(2)

We can rewrite equation (2) as x-3y=16----------------(3)

Now, Eliminate equation (3) from (1), we get

y-(-3y)=128-16\\\\\Rightarrow\ 4y=112\\\\\Rightarrow\ y=\dfrac{112}{4}=28

Substitute the value of y in (2), we get

x=3(28)+16=84+16=100

Hence, the team won 100 games and losses 28 games.
