Hello 20. We're going to solve a problem. Number 37 here. My took a equals three one for so five A is equals to 15. Fine 20 right. Determined off five is equal to 1 50 minus 100 which physicals 15 five in the determinant. A calls. So I even do 86 minus four five in the two, which is so five Indian determined A is not equal to determent off. Find it.
