Find a basis for the following plane in R x - 5y + 4z = 0 First, solve the system, then assign parameters s and t to the free variables (in this order), and write the solution in vector form as su + tv. Below, enter the components of the vectors u = [u, U2, U3] and v = [V1, V2, V3]. U1 U2 Uz and V1 V2 V3 || || ||
