Hello there, I just solve the problem as David Joyner explained. Here is the code:
sage: var('w1,x2,x,y') (w1, x2, x, y) sage: U=x+2*y sage: V=(3*x)+(4*y) sage: W=(w1*x)+(4*y) sage: Z=((-2)*x)+(x2*y) sage: solve(2*u==w,w1) [w1 == 2] It´s not all done but is just a matter of putting solve and the problem to solve. Thanks David :-) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sage-edu" group.
