Use the constants to replace the y -coefficients. Use the constants to replace the z -coefficients.
Therefore, The check is left to you. The solution is x = 1, y = –2, z = –3. If the denominator determinant,

Unformatted text preview: D , has a value of zero, then the system is either inconsistent or dependent. The system is dependent if all the determinants have a value of zero. The system is inconsistent if at least one of the determinants, D x , D y , or D z , has a value not equal to zero and the denominator determinant has a value of zero....
