Answer:

Infinite solutions

Step-by-step explanation:

2x−7y=12 (1)

−x+3.5y=−6 (2)

(2) x = 3.5y + 6

(1) 2(3.5y+6) - 7y = 12

7y + 12 - 7y = 12

12 = 12 (a true statement)

Since the variable got eliminated and we got a true statement, the system has infinitely many solutions.

One of the solutions:
