First, we write the two equations given.
"Nancy's sales last week were $140 less than three times Andrea's sales"
We write this as:
N=3A−140
"together they sold $940."
We write this as:
N+A=940
Solve for A:
A=940−N
Substitute A into first equation:
N=3(940−N)−140
Distribute:
N=2820−3N−140
Add like terms and simplify:
4N=2680
Solve for N:
N=670
Plug N into second equation:
670+A=940
Solve for A:
A=270
Final Answer: N=670,A=270

I came across the following question:
Let V be the real vector space of polynomials with degree 2. For α , β R let W α = { f V | f ( α ) = 0 } and D β = { f V | f ( β ) = 0 }. f describes the derivative of f.
Find a basis for W α and D β .
Unfortunatly I am not quite getting my head wrapped around vector spaces with polynomials yet. So after failing the question I had a look at the solution and there it says:
By solving the system of linear equations:
W α : { X α , X 2 α 2 }
D β : { 1 , X 2 2 β X }
More explanation is not given.
I know that the elements in W α in the form of f ( x ) = c 2 X 2 + c 1 X + c 0 are zero at α, so f ( α ) = c 2 α 2 + c 1 α + c 0 = 0.
Respectively for the elements in D β : f ( β ) = 2 c 2 β + c 1 = 0.
However, it is not clear to me how I get from that information to the basis of W α and D β using systems of linear equations.
