Let a11 x1 + a12 x2 + a13x3 = b1. a21 x1 + a22 x2 + a23 x3 = b2. a31 x1 + a32 x2 + a33 x3 = b3. Show that if det (A) 6= 0 where det (A) is the determinant of the coefficient matrix, WebOct 7, 2002 · Original question: a11x1 + a12x2 = b1. a21x1 + a22x2 = b2. If a11a22 - a12a21 != 0, then prove that this system is equivalent to: c11x1 + c12x2 = d1. c22x2 = d2. where c11 and c22 != 0. I solved it by setting the cross product equal to a constant (cA) that's not equal to 0, then doing a row reduction where a21 is set equal to a constant (cB ...
