Question

15 POINTS
Solve using the elimination method

Answer 1

x = 4

y = 11

Explanation:

x + y = 15 Eq. 1

5x - y = 9 Eq. 2

_________

6x + 0 = 24

6x = 24

x = 24/6

x = 4

From Eq. 1:

x + y = 15

4 + y = 15

y = 15 - 4

y = 11

Check:

From Eq. 2

5x - y = 9

5*4 - 11 = 9

20 - 11 = 9

Answer 2

Use 1 equation plus the 2 equation

5x + x + y - y = 24

6x = 24

x = 4

4 + y = 15

y = 11
