.


Divide 1-st equation by 2 and then write in the STANDARD form.


Divide 2-nd equation by 4 and then write in the STANDARD form.


You will get


    3x - y = -1

    3x - y = -1


Looking attentively, you see that these two equations are IDENTICAL.


THEREFORE, they have infinitely many solutions, representing the straight line


    y = 3x + 1.     (*)


Variable "x" may have any real value, and variable "y" has the real value according to the formula (*)
