Method 1, 2x+3y=16
x+4y=13 ②
From x=13-4y
Bring in the got.
2(13-4y)+3y=16
26-8y+3y=16
5y=10y=2 y=bring in x=13-8=5
Method 2, 2x+3y=16
x+4y=13 ②
2 gives 2x+8y=26
Get 5y=10
y=2 brings y=2 into .
x+8=13

If you win x games and draw y games, you lose (4-x-y) games. 3x+1y+0(4-x-y)=6 3x+y=6 y=6-3x When x=0, y-=6-3 0=6 (rounded) When x=1, y=6-3 1=3. When x=2, y=6-3 2=0 When x=3, y=6-3 3=-39 (rounded) So draw 2 games, win 1 game or win 2 games, draw 0 games.
