The  y -numerator determinant is formed by taking the constant terms from the system and placing  them in the  y -coefficient positions and retaining the  x- coefficients.  The answers for  x  and  y  are as follows:  The check is left to you. The solution is  x  = –5,  y  = –2.  Many times, finding solutions by using determinants is referred to as
