  1. $x=2,y=6$
  2. $x=3,y=6$
  3. $x=4,y=6$

  4. None of these

A Correct answer
Explanation

From the second equation, x=2. Substituting into the first equation: 3(2) - y = 0, so y=6.

AI explanation

The second equation directly states that x - 2 = 0, which means x = 2. Substituting this value into the first equation, 3x - y = 0, results in 3(2) - y = 0. Solving for y gives y = 6, so the solution to the system of equations is x = 2 and y = 6.
