Re: help me in c++

I don't have code but here is the way to start

3 equation 3 unknown can be solve using the Cramer's Rule..

so just review Cramer's rule learn how to use the determinant of the coefficient matrix and develop D1 D2 and D3 matrixes... most likey u need to use 3D array to implement them

I hope this would help

Good Luck!
