WebThe Matrix Solution. We can shorten this: to this: AX = B. where. A is the 3x3 matrix of x, y and z coefficients; X is x, y and z, and; B is 6, −4 and 27; Then (as shown on the Inverse of a Matrix page) the solution is this:. X = A-1 B. What does that mean? It means that we can find the X matrix (the values of x, y and z) by multiplying the inverse of the A matrix by the B … WebIf a, b, c are non-zero real numbers and if the system of equations (a – 1)x = y + z, (b – 1)y = z + x, (c – 1)z = x + y, has a non-trivial solution, then ab + bc + ca equals abc. Explanation: Given system of equations can be written as (a – 1)x – y …
