HELP ALGEBRA!!! plz... I need to do this equation: What is the value of the system determinant: 2x - y = 5 x + 3y = 7 What is a system determinant? X? Y? Do I need to convert this to a matrix, and if so, how?

jimthompson5910 (jim_thompson5910):

you just write the coefficients on the left side into a 2x2 matrix

jimthompson5910 (jim_thompson5910):

then you take the determinant of that 2x2 matrix
