Answer
Explanation:
Step1: Check first equation
Substitute (x = 8), (y = 3) into (-x + 4y = 4). Left side: (-8 + 4\times3 = -8 + 12 = 4). Right side: (4). So first equation holds.
Step2: Check second equation
Substitute (x = 8), (y = 3) into (-x + 3y = 1). Left side: (-8 + 3\times3 = -8 + 9 = 1). Right side: (1). So second equation holds.
Answer:
A. Yes
