Using the simple national income model:

Using the simple national income model:

         Y = C + Io + Go

                 C = a + bY          

   where Io and Go are exogenous variables, and Y and C are endogenous variables, and a, b are constants.

Set up this model in a matrix form and solve for: Y, C in terms of Io, Go, a, and b

D. Determine the impact of changes in Go and Io on Y and C.

I need a clear answer in detalis with econmics analysis or explantions .. thx
