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

I’m not sure what sujevtbis this

20000 as first it increases by 2500 then by 5000 so next it will increase by 10000
