<prompt> Matricesanzapmatrix 2 a -3 -1 mwishopmatrix quad textna quad anzapmatrix -frac116 b frac316 na frac18 endpmatrix ni kinyume. Weka jozi iliyoagizwa a,b.  <response>: Bidhaa ya matrices nianzapmatrix 2 a -3 -1 mwishopmatrix anzapmatrix -frac116 b frac316 frac18 endpmatrix anzapmatrix frac3a16 - frac18 fraca8 2b 0 -3b - frac18 endpmatrix.Tunataka hii iwe kiini cha utambulisho, kwa hivyo frac3a16 - frac18 1, fraca8 2b 0, na -3b - frac18 1. Kutatua, tunapata a,b left 6, - frac38 kulia.
