So we're wanted to know how many days the second voice lasted, and we know that the total was one thousand and three. So we know one thousand and three is a amount for the first plus the segment. Well, we're told that the first voyage lasted forthree days longer than the second voice. So we can say first is equal to second plus forty three. So then you can take this amount and plug it back into the first because we have a first year in first year. So I'm just gonna substitute this back into here. Who wants a one thousand three secret? A second plus forty three plus signed. So I'm just going to call the second s. And so then I have one thousand three is going to ask if we fucked two of those. Plus the forty three I'm here. I'm gonna subtract forty three from both sides, giving me some going over here. So then we have to us on the right side, and they're on the left side. We have nine hundred and sixty, So from here, I'm going to five both sides by two to finally isolate. That s then if I do nine. Sixty defined aboutyou. I get four hundred eighty.
