Assignment:
Solve by graphing, indicate whether each system is independent, inconsistent, or dependent.
Q1. x + y = 5
x - y = -1
Q2. y = -x
y = -x + 3
Solve by substitution, indicate whether each system is independent, inconsistent, or dependent.
Q3. x - y = 3
3x - 2y = 3
Q4. 2x - y = 3
6x - 9 = 3y
Solve by the addition method, indicate whether each system is independent, inconsistent, or dependent.
Q5. -3x + y = 3
2x - 3y = 5
Q6. 5x - 3y= -20
3x + 2y = 7
Solve each system by the method of your choice. (indicate the method)
Q7. 3x - 2y = 8
x = -2y
Q8. 4y = -5x
5x + 8y = 20
Provide complete and step by step solution for the question and show calculations and use formulas.
