Linear algebra problem

This problem was confusing me so any explanations would be helpful and greatly appreciated!

Examine S

R^5 defined by

S = {x_1, x_2, x_3, x_4, x_5

R^5|x_2 = 0, x_3 + x_4 = x_5}.

Verify that the subset S is, in fact, a subspace.

Re: Linear algebra problem

Because they are not linearly independent? I guess this accounts for the suffix "sub".
