Question

Solve x + 2y = 13
4x + 8y = −9

Answer 1

no solution

Explanation:

Answer 2

This system of equations is inconsistent. It describes two parallel lines, so has no solution.

If you mulitply the first equation by 4, you get

... 4x + 8y = 52

There are no values of x and y that will make 4x+8y sum to both -9 and 52.
