Answer 1

Answer:

y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0

Step-by-step explanation:

y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20 = 0y − 5 = 0 and 3x + 4y − 20

Answer 2

$(1999 + 1) + (1998 + 2) + (1997 + 3) + (1996 + 4) \\ = 2000 + 2000 + 2000 + 2000 \\ = 8000$
