I think you basically just got to add everything up . I mean , i can already tell this is a graph question but it says perimeter so perimeter somehow means add everything up. But im still not too sure ..

Answer:
Multiply the second equation by -3 to get -3x - 9y = -30.
Step-by-step explanation:
When eliminating, you need to find a term with the negative of that term to combine so that they cancel each other out. An example would be 3x in the first equation and (-3x) in another equation so that when added, it becomes: 3x-3x = 0.
In the second equation, you see that there is already an x there and you just need to make it become (-3x). Thus, you multiply the entire second equation by -3 to make -3x. Once you have done that, you can combine the two equations and eliminate 3x from the first equation.
3x + 5y = 30
-3x - 9y = -30
3x + 5y -3x - 9y = 30 + (-30)
0 - 4y = 30 - 30
-4y = 0
<em>You can find y and then x later on from here. </em>
