What is the solution of the system? use the substitution method. {y−2x=816 4x=2y the only solution is (24, 0) . the only solutio

Butoxors [25]

To determine the answer it would be helpful if we write this equation into the slope intercept form which is expressed as:

y = mx+b

<span> y−2x=816
y = 2x + 816

4x=2y
y = 2x

We can see that the slope of the two equations are the same. Therefore, they are parallel which means they do not intersect. The correct answer is the third option, there is no solution.</span>
