When solving the system of equations 3x – y = 6 and y = 2x + 4, what is the value of x?

  1. 4

  2. 5

  3. 6

  4. 7

The correct answer is: 6

The value of x can be found by substituting the value of y into the first equation. 3x - (2x + 4) = 6 Although options A, B, and D all satisfy the second equation, only option C satisfies both equations and results in a true statement. This means that the solutions for this system of equations is x = 6 and y = 16. The other options are incorrect because they do not result in both equations being satisfied.
