WebMar 16, 2015 · I have been doing some practice questions for university, and one of them is regarding row reducing a complex matrix. From what I can work out, I think (i could very well be wrong) that the first unknown (row 1) should be (1/32) (41i - 82) And as such, the second unknown should be (-3-2i) - (2 + 2i) ( (1/32) (41i - 82))
