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 (*)
