Express v = (3, 7, -4) in R3 as a linear combination of the vectors
u1=(1, 2, 3); u2 =(2, 3, 7); u3 =(3, 5, 6)
We seek scalars x, y, z such that v = xu1 + yu2 + zu3

I recovered the removed content from the Google cache (something which anyone can do). Editing away your question is very rude. Someone spent time reading your question, understanding your issue, figuring out the solution, and writing an answer. Now you repay that kindness by ensuring that the next person with a similar question can't benefit from this answer.

b = [3, 7, -4]' ;
u1=[1, 2, 3];
u2 =[2, 3, 7];
u3 =[3, 5, 6] ;
A = [u1' u2' u3'] ;
x = A\b ;
% check
[A*x b]
ans = 3×2
3.0000 3.0000 7.0000 7.0000 -4.0000 -4.0000
