System of Equations

Describe one thing that you enjoyed doing this past weekend.

Add the two equations.

 $-3x-5y=22$  

Add the two equations. 

 $4x-10y=8$  

 $-4x-8y=28$  

Subtract the equations.

Subtract the equations.

 $-3x-9y=3$  

 $-3x-6y=9$  

How can we use multiplication to adjust one the equations in order to help us eliminate one of the variables?

 $-14x+6y=-18$  

 $-7x+9y=-27$  

Example answer: "..Multiply the first equation by 3"

How can we use multiplication to adjust one the equations in order to help us eliminate one of the variables?

 $5x+10y=20$  

 $-10x+y=2$  

Example answer: "..Multiply the first equation by 3"

How can we use multiplication to adjust one the equations in order to help us eliminate one of the variables?

 $4x-y=2$  

 $3x+2y=29$  

Example answer: "..Multiply the first equation by 3"
