Answer:
4x2=y
3x8=y
Explanation:
Because there are no x's or other factors you just need to write another equation. You can use whatever numbers you want as long as it isn't equal to 4x2 which is 8. So you can use and numbers that will not multiply to 8.
When this happens then there is no y value that could be the same for each equation and therefore no solution that fits them both.
