we have this equation. We know that one route is equal to negative three. We also know that if we take a route plus the other route that's gonna equals negative B over a. So it's just plug in what we know. One route is equal. Negative. Three. We don't know another roots. Let's just call it rude to And we do know Herbie Value is negative. Eight. So a negative negative eight is like a positive. We know our values. One in 8/1. Let's just rewrite that as eight. And there we go. So negative three plus what equals eight. Well, we can do a little bit of algebra and maybe you guys can already see it. If I add three. This goes away. If I add three, then we get our final answer of that other route is equal to 11
