What is the solution to this system of linear equations? y − x = 6y + x = −10(−2, −8)   (−8, −2)(6, −10)(−10, 6)

These ratios are not equivalent.

Step-by-step explanation:

If you get 5 pairs of socks for $15, that means that each pair of socks are $3. If you buy 10 pairs of socks for $25, you are spending $12.50 for each pair. If you double the 5 pairs of socks for 10 pairs of socks, you will be spending $30 because you have to add another $15.

So between 10 pairs of socks for $30 (5 pairs of socks for $15) and 10 pairs of socks for $25, you will be spending more on the 5 pairs of socks.

You are spending more money on the 5 pairs of socks for $15.
