WebFor (a), arguing by contradiction, let x, y, z \in \mathbb{Z}_{+} such that 2 a b c-a b-b c-c a=x b c+y a c+z a b. Then. 2 a b c=(x+1) b c+(y+1) a c+(z+1) a b. so that a \mid(x+1) b c. Since \operatorname{gcd}(a, b c)=1, we conclude that a \mid(x+1) and, hence, that x+1 \geq a. Similarly, y+1 \geq b and z+1 \geq c. But these give WebJun 12, 2015 · 30. There are two ways to approach this problem: numerically and symbolically. To solve it numerically, you have to first encode it as a "runnable" function - stick a value in, get a value out. For example, def my_function (x): return 2*x + 6. It is quite possible to parse a string to automatically create such a function; say you parse 2x + 6 ...
