Systems of Equations by Elimination

 $-2x\ +\ 4y\ =10$ 

 $x-y=-1$  

Answer explanation

Put No Spaces Between Parenthesis, Commas, Numbers.

 $-2x+4y=12$ 

 $-8x-6y=4$  

 $3x-3y=9$ 

 $5x-6y=14$  

 $-3x+6y=-18$ 

 $5x-3y=-5$  

 $-6x-6y=-18$ 

 $3x+2y=7$  

 $-9x-3y=-9$ 

 $3x-6y=3$  

 $6x-4y=18$ 

 $-2x+6y=8$  

 $-5x-2y=5$ 

 $-6x-5y=-7$  

 $-4x+5y=3$ 

 $-5x+4y=-3$  

 $4x+5y=-8$ 

 $-3x-6y=6$
