Code:
3x = 30 x=10
2y + x = 20 substitute x
2y + 10 = 20
2y = 10 solve for y
y = 5
2z + y = 13 substitute y
2z + 5 = 13
2z = 8 solve for z
z = 4
x/2 + z/2 * (y + x + z) = ?
5 + 2 * (5+10+4) = 43 + k order of operations always prevails
Edit: Edited because I missed that the two rolled-up blankets become just one in the final equation.
Edit2: Yeesh. And missed that there is only one shoe in the final equation also. No wonder there's so many answers.
Edit3: And. Yes. Every time I look at it, there's more that I missed the first time. **** this guy. It isn't a math question, it's an
attention to detail test. One that I failed miserably.
Edit4: There is no correct answer. He put on some wristbands in the final equation. We have no idea what value is put on those.
