Answer:
y = -8
Step-by-step explanation:
Solve as a system of equations
2x + y = -8 multiply this equation by 2
-4x + 2y = -16 Do not change
Solving: 4x + 2y = -16
<u> -4x +2y = -16 </u>
4y = -32
y = -8
2x + y = -8 Solve for x
2x = -y - 8
x = -y/2 - 8/2
x = -1/2y - 4 Substitute this into your second equation
-4x + 2y = -16
-4(-1/2y - 4) + 2y = -16
2y -16 +2y = -16
4y - 16 = -16
4y = -32
y = -8 x = -1/2(-8) -4 = 4 - 4 = 0
Checking the answer
2(0) + -8 = -8
-4(0) +2(-8) = -1 6 = 0 -16 = -16

Answer:
27 more games
Step-by-step explanation:
The team has played 75 games so far. Theyve won 50 out of 75 of those games. They still have 45 games left to play. That's 120 games in total. 60% of 120 is 72. They have to win 72 games in total. 72 - 45 = 27. They need to win 27 more games in order to have won 60% of all the games theyve played.
