What is the solution to the system of equations? Use the linear combination method.

{2x-3y=9

{3x+5y=4

1. {2x-3y=9

{3x+5y=4

2. { (2x-3y=9) * 5

{ (3x+5y=4) x3

3. {10x-15y=45

{9x+15y=12

4. (10x-15y=45) + (9x+15y=12) = (19x=57)

5. (19x=57) : 19

6. x=3

7. 2 (3) - 3y=9

8. 6-3y=9

9. - 3y=9-6

10. (-3y=3) : (-3)

11. y=-1

Answer: x=3 and y=-1
