Correct Answer:
B. 2
To find the value of x from the given system of linear equations, we can use the elimination method. The equations are:
- x + y = 6 (Equation 1)
- 4x - y = 4 (Equation 2)
Notice that the 'y' terms have opposite signs. By adding Equation 1 and Equation 2, the 'y' terms will cancel out:
(x + y) + (4x - y) = 6 + 4
5x = 10
Dividing by 5 gives x = 2. Options A, C, and D are incorrect values that would not satisfy both equations simultaneously.
