For each a ER we define the following two subsets of R³: Sa := {[x, y, z] E R : ax + (a² + 4a – 5)y³ + 3z = 0} %3| and Ta := {[x, y, z] E R³ : 2x + 4y – (a – 1)²|z| = a² – 3a + 2}. Find all a e R such that the intersection San Ta is a subspace of R³. (You may assume the following fact: S,T both subspaces SNT is a subspace.)

Please help me with this question!

For each a ER we define the following two subsets of R³:
Sa := {[x, y, z] E R° : ax + (a² + 4a – 5)y³ + 3z = 0}
||
and
Ta
{[x, y, z] E R³ : 2x + 4y – (a – 1)*|z| = a² – 3a + 2}.
Find all a E R such that the intersection San Ta is a subspace of R³. (You may assume
the following fact: S,T both subspaces SNT is a subspace.)
