lol never taken a test where all of the multiple choice answers were the same, but if I did it would certainly mess with me psychologically and I would probably repeat my work just to be sure.

How do you substitute x+7y=0 into 2x-8y=22
Grace [21]
First solve for x in the first equation

x + 7y = 0
x = -7y

since x = -7y we can substitute -7y into the other equation wherever there is an x

2x - 8y = 22
2(-7y) - 8y = 22
-14y - 8y = 22
-22y = 22
y = -1

Now let's substitute -1 back into either of the original equations so we can solve for x

x + 7y = 0
x + 7(-1) = 0
x - 7 = 0
x = 7

So your solution set is

(7, -1)

Step-by-step explanation:

Perimiter is width plus width plus length plus length and they give you the width but since there is two widths you have to add the widths then subtract that from 11 1/5 and the answer from that gets divided by two.

If wrong let me know and i will try again
