Answer:
Answer:
8x + 7y = 30 ( one solution)
8x - 7y = 2
-8x + 7y = -2 ( infinitely many solutions )
8x - 7y = 2
8x - 7y = 2
-8x + 7y = 2 ( zero solutions )
Step-by-step explanation:
Answer:
8x + 7y = 30 ( one solution)
8x - 7y = 2
-8x + 7y = -2 ( infinitely many solutions )
8x - 7y = 2
8x - 7y = 2
-8x + 7y = 2 ( zero solutions )
