Because if x is greater than y, then x-y wouldn’t be below 0 like it’s shown, so x must be less than y.
And if x is less than y, any negative y would mean x is negative as well since it’s always less than y. And as shown, x+y is positive so it’s impossible for y to be negative.
+17 bc you want to do the opposite so then it’s 17+10 which gets you x=27
2x-4 D it can be your answer if you multiply correctly and you do it
