If a(0,1,3)+b(1,1,1)c(1,2,5)=(2,3,8), determine a,b,c

I am assuming that a , b , and c are scalars and this is scalar multiplication , if so, then
b  c = 2
a + b 2c = 3
3a + b  5c = 8
you got 3 equations in 3 unknowns, should be easy
I will start you off....
subtract the first two
a+c=5
subtract the last two
4a + 3c = 11
take it from there
