Hello everyone,
I'm sure someone can help me to solve this problem I'm having right
now. It's about vectors and it's really easy when you do it on paper
but it becomes a little tricky when you try to solve it in sage.

This is the problem:
Let be u=(1,2), v=(-3,4), w=(w1,4), x=(-2,x2) where w1, x2 are
integers.
Find w1 and x2 if
a) w=2*u
b) (3/2)x=u
c) w+x=u

Please help me with the adecuate code to solve this problem.
Thank in advance,
Daniel Gonzalez ;-)
