Answer:
That question’s impossible because the corresponding coefficients and constants aren’t proportional by the same factor.
The coefficient of the x term in the second equation is 4x larger than that of the x term in the first equation. Therefore, the second equation’s constant should also be 4x larger than the first equation’s constant.
So if the second equation’s constant was 28 instead of 0, then there could be infinitely many solutions (k would equal 8).
