Given:

4x - y = 4

x + 2y = 2

To find:

We need to find out whether (4,0) is the solution of this system of equations.

Step-by-step solution:

We will firstly solve this system of equations, using the elimination method:

4x - y = 4.......(1)

x + 2y = 2......(2)

We will firstly multiply the equation (1) with 2 and then add both equations.

8x - 2y = 8.......(1)

x + 2y = 2......(2)

Upon adding both equations:

9x = 10

x = 10/9

2y = 2 - 10/9

2y = 8/9

y = 4/9

Final answer:

Thus the ordered pair satisfying the equations is equal to (10/9, 4/9).

Given ordered pair (4,0) does not satisfy the system of equations.
