vector space prob

[ffffff]

v = ( 4, 4, 5 ), a = ( 1, 2, 3 ), b = ( -2, 0, 1 ), c = ( 1, 0, 0 )

v, a, b, and c are vectors

ca'i problem la` la`m sao dde^? write v as a linear combination of a, b, and c

ne^'u ho^ng ddu+o+.c thi` ta.i sao ?

[chubuha]

assume that you can write it
so v = ax + by + cz
4=x-2y+z
4=2x+0y+0z
5=3x+y+0z

and then it is your work
find the solve of this system

good luck
