All right. So we have Why is minus five X here? So we need to do is plug it into the next equation. So we'll get X plus three times minus five x his minus 28. So that'll be X minus 15 X is minus 28. So we know the X minus 15 X that's minus 14. X is equal to minus 28. Let's divide both sides. My minus 14. So X is too since X is to we need to plug it into the first equation here. Why is minus five X So since we know that, why is minus five X? All we need to do is plug in X here. So why is equal to minus five times two? So why is negative 10?
