Okay, So where's the fact that of falling? So let's use the group in method. So we have a that's equal to Tony. We eat that stable to negative 90 days and see that's equal to that of the 35 our key number physical to eight times she, which is 20 times, were different fight and that was me thinking of 700. So we need to numbers. These products are negative 700 whose some is equal to be, which is negative. 93. Okay, so I can take the number seven as well as 10 are sorry. Seven and 107 times 100. Give me 700. Um, and now, if I subtract or take the negative of 100 we get the product equaling negative. And so as something. So let's put the middle number into negative 100 x plus seven x, and they get minus 35 20 white squared Now can factor. Oh, sorry. You should be What is actually, in fact, the 1st 2 terms. By pulling out a 20 wine when we get 100 divided by 20 that's equal to Y minus five. Anything I can factor out. He's seven from our last two terms. Excuse me. Y minus five. And now we can see that Are y minus five House? Um, we contracted out since we have these two terms in common, So we get Y minus five times 20. Why? Plus seven.
