The ordered pair which is a solution of the system of equations is; (4.9, 0).
The equations given in the task content can be solved as a system as follows, since y = y;
4x -19.4 = 0.2x -4.2
4x -0.2x = 19.4 -4.2
3.8x = 15.2
x = 15.2/3.8
x = 4.9
y = 4(4.9) -19.4
y = 0.2
Hence, the best ordered pair solution is; (4.9, 0).
