Question

Which of these system of linear equations has no solution

A. 2x+8y=15
4x+16y=30

B. 2x-y=18
4x+2y=38

C. 4x+7y=17
8x-14y=36

D. 4x-3y=16
8x-6y=34

Answer 1

D

Explanation:

You have to find a slope but when you apply the slope to the intercept the intercept can not be equal to the neaver mind i suck at explaining.

Answer 2

A

Explanation:

Those two lines are the same. If you divide the second equation by 2, you will end up with the first equation. A system of linear equations cannot have two of the same line.
