1. Let A∈ Μ4,3 (that is, a 4 x 3 matrix). Let v1, v2 ∈ R^4 and let w = v1 +v2. Suppose there exists u1, u2 as an element of R^3 such that v1 = Au1 and v2= Au2 prove the Ax=w is consistent 2. Relevant equations 3.i honestly don't know if i'm doing this correctly at all, but this is what I have done so far: Ax=w where A is a 4x3 matrix. Ax=v1 + v2 Ax=Au1 + Au2 then i don't know what to do.
