Generally what duration it takes to complete it. Did any one try solving it before And got one and solve it now and then.

My formula was this: You just need the first equation. If $8=56$ then $8(3-\pi)=56(3-\pi)$ then $24-8\pi=168-56\pi$ Now move stuff around and get $56\pi-8\pi=168-24$ so $48\pi=144$ thus $\boxed{3=\pi}$ The same thing seems to happen if I do it to the other equations, thus the others are just extra unnecessary information. $\square$

Your work gives $$8(3 - a) = 56(3-a) \implies 48(3-a)=0$$ and so clearly $48 = 0$ or $a=3$. The method you use can therefore prove that $3$ is equal to anything you want it to be. Except that $$48(3-a)=0 \implies (56 - 8)(3-a)=0$$and the first line gives us that $56 = 8$, so we get no information about the value of $3-a$. Last edited by greg1313; May 10th, 2015 at 07:04 PM.
