Okay, So in order to solve this problem again, we're going to define our variables game so less use different variables this time. So we let TB the number off consumption or consumption. Oh, chicken annual pretty capital. All right. And then we'll have B B, the consumption off MIF. And according to the problem, the consumption first in IHS £6.3 less than that of the beef. So the consumption chicken is actually the consumption of beef minus 6.3 bounce and on the average, the total consumption that they have. So that seat must be s one of journey £0.5 off. She can. Okay, so this will be our system off inner creations, and we're going to use the substitution. Buy something, shooting the first equation to the value of see in our second equation. Okay, so the second equation becomes B minus six point C, which is the value off seeing the first creation and then plus B ecause 120.5, a combined similar turns. You have to be minus explained three because 120 25. Okay, and add in 6.3 on both sides of vacation got to be caused. 129.5 thus explained. Okay. And then we have to be recalls 126 point and sold him for B. We divide both sides by two chancel out to we got me. He call 63 going for bounds off leaf here. Next in order. So for the consumption of chicken, we'll use either the first or the second equation is substituting the value of B. We have calculated earlier bought for easier calculation will use the perspiration course. So we have C calls. U minus. Explain three. To that, C equals 63.4. My nurse six pointy. Okay. And so calculating. The will get, uh, if the seven point all bounds off chicken consumption of chicken, okay?
