Question:

(a) Evaluate the matrix product Ax, where and 3 х х— and x= У A

Hence show that the system of linear equations
7x + 5y = 3
x + 3y = 2
can be written as Ax = b where 3 ь 2.

(b) The system of equations
2x + 3y − 2z = 6
x − y + 2z = 3
4x + 2y + 5z = 1
can be expressed in the form Ax = b. Write down the matrices A, x and b.
