{"Image DocumentName": "Follow-up Solving Equations by Inverses of Matrices", "Image ImageDescription": "Determine the number of solutions to the following. systems of linear equations. (a) (b) Solution: (b) Rewrite the system of equations as . \\ The system does not have a unique solution. Consider. (1) \uf0b4 3: 9x + 3y \uf03d 3\u2026\u2026\u2026\u2026(3) Since (2) and (3) are the same, we say that equation (2) is redundant and the linear system has only one equation 3x + y \uf03d 1. Therefore, the system of linear equations has infinitely many solutions.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
