Consider the following system of linear equations:
3x_(1)+9x_(2)+9x_(3)=-2
6x_(1)+19x_(2)+18x_(3)=-2
9x_(1)+30x_(2)+30x_(3)=-4
This system is equivalent to the vector equation Ax=b where
A=[[3,9,9],[6,19,18],[9,30,30]] and b=[[-2],[-2],[-4]]
Calculate the inverse of the matrix A :
Use A^(-1) to solve the system of linear equations above.
[[x_(1)],[x_(2)],[x_(3)]]=[◻]
