ACTIVITY # 1

-
A. Is ( 1, 5) a solution of each system of equations?

1. x + y = 4
-
x = 1 _______________

-
2. y = x + 4
-
y = 0.2x _______________

3. y = 5
x = y – 6 _______________

-
4. 2x – y = 7
y = x + 6 _______________

Which method would you use to solve the system of linear equations? Explain why.

5. y = 4x – 8
y = 2x + 10

____________________________________________________________________________

6. y = x – 2
2x + 2y = 4

____________________________________________________________________________

7. 3x – 6y = 30
6x + y = 34

____________________________________________________________________________

8. y = 3
-
2x + y = 15

____________________________________________________________________________

9. 5x + 4y = 5
y = 5x
