- i cannot figure out where the 3z comes from

The question is asking to express a polynomial in terms of 3 other given polynomials, which in this case should be very straight forward but i am having issues, with the end terms on the second line they have grouped the constants that have a t^0. They have put 5x+3z, my answer says 5x+z, because they're the only terms with t^0 attached. Every other part of the answer matches mine apart from that one term, which ultimately changes the whole final answer. what am I missing?
