Question

Use the elimination method to solve the system of equations. Choose the correct ordered pair.

–x + y = –3
3x + 2y = 9

Answer 1

`-x + y = -3; 3x + 2y = 9 :| \text{Solve}`


`-2x+2y=-6; 3x+2y=9`


`-5x=-15`

___________________________________________________


`-5x=-15`


`x= (-15)/(-5)`


`x= (15)/(5)`


`x=3`

___________________________________________________


`-2*3+2y=-6`


`-6+2y=-6`


`2y-6=-6`


`2y=0`


`y=0`

____________________________________________________


`x=3; y=0`
