give an example for a set of linear equation (from field R) that has the following

general solution:

??

i wrote a matrix

and inputed alpha=1 and beta=2

and this is my answer

is that ok?

i need to give an example so the set that i was given

would be its general solution(i guess i need to present one case)

i have constructed this general matrix:

1 a b

2 a b

3 a 0

and inputed some a=1 b=2

but i am not sure if this the correct way of solving it??
