Part 1: Explain, in complete sentences, how you would use the elimination method to solve the following system of equations. (4 points) 

Part 2: Provide the solution to the system. (2 points) 

5x – 9y = –16 
2x + 6y = –16

anonymous · Answer

i would multiply the first equations by $2$ and the second equation by $3$
that would give 
$$10x-18y=-32$$$$6x+18y=-48$$
then i would add the two equations together to get 
$$16x=-80$$
divide by $16$ to get $x=-5$

Thank u!!

anonymous · Answer

now that you know $x=-5$ you can substitute $-5$ for $x$ in either equation and solve for $y$

anonymous · Answer

$$2(-5)+6y=-16$$$$-10+6y=-16$$$$6y=-6$$$$y=-1$$
