4- Systems of Linear Functions
Solve the following systems by each of the following methods: Substitution, Elimination,
Determinants (Cramer’s Rule), Augmented Matrices, Graphing, Inverse Matrices. Attach any
additional sheets of paper you used to complete the different methods.
1. 2x + y = 3
2. 7x + 3y = 6
3. x – 5y = -6
x - 4y = -3
5x - 2y = 25
3x – 6y = 0
Solve each of the following systems by a different method: substitution, elimination,
determinants, and augmented matrices.
4. 2x - y - z = 6
5. 3x + 2y - z = 3
x + 5y + 3z = -10 x + 4y - 4z = 7
3x - y - 5z = 4
-2x - 3y + 5z = 0
