Can we solve matrix in Excel?
To solve using matrices, use the equation Ax=b where matrix A is the coefficient matrix, x is the variable matrix and b is the matrix of given solutions. Therefore, x=A-1*b. The A^(-1)*b matrix is the matrix with values of x, y, and z. This gives the answers x= 4.71, y= -1.026 and z= 3.113.
