Please share with us also the code you have already done. If this is the
code that we see this morning is something like this (there could be
errors but I don't remember all the code):
var('w1,x2')
u = vector([1,2])
v = vector([-3,4])
w = vector (w1,4])
x = vector([-2, x2])
answers = []
for i in range(2):
asnwers.append(solve(w == 2 * u)
answers
We get something with four responses, but the question is: how can I
solve vectorial ecuations like v = 2*u if there are variables and
numbers in the vectors?
Cheers,
Offray
