What is the set up for the coefficient determinant (D) in the following system? 4x – 3y = 16 3x + 7y = –25
the coefficient determinant is just the determinant of the matrix that is formed from all the coefficients you find on the left side
Do you add or multiply the coefficients from the left to equal the determinant of the matrix?
just write them down into matrix form
the coefficients for 4x – 3y are 4 and -3 they form the first row of the matrix
