Use the elimination method to solve the system of equations. choose the correct ordered pairs - x + y=-3 and 3x + 2y=9

-x+y=-3, 3x+2y=9

1. multiply the first row by the second

-2x+2y=-6, 3x+2y=9

2. subtract the second row from the first row

-5x=-15

3. sole for x in the above equation

x=-15/-5

x=15/5

x=3

4. substitue x=3 into - 2x+2y=-6

-2*3+2y=-6

5. solve for y in the above equation

-6+2y=-6

2y-6=-6

2y=0

y=0

6 therefore,

x=3 and y=0

Have a nice day : D
