How do you solve linear equations in Excel?

To solve this system of linear equations in Excel, execute the following steps.

  1. Use the MINVERSE function to return the inverse matrix of A.

How do you use Excel to solve a system of linear equations using matrices?

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.
