Question

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

–x + y = –3
3x + 2y = 9

Answer 1

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

$-2x+2y=-6; 3x+2y=9$ 

$-5x=-15$ 

___________________________________________________

$-5x=-15$ 

$x= \dfrac{-15}{-5}$ 

$x= \dfrac{15}{5}$  

$x=3$ 

___________________________________________________

$-2*3+2y=-6$ 

$-6+2y=-6$ 

$2y-6=-6$ 

$2y=0$ 

$y=0$

____________________________________________________

$x=3; y=0$
