Step-by-step explanation:
You can first multiply the width by two. Then you subtract that from you perimeter to figure out your length. Whatever number you get divide it by two and there's your length.
Example:
Perimeter =30 Width=5
5 times 2= 10
30-10=20
20/2=10
So your length equals 10.

Answer:
y= -2x - 5
Step-by-step explanation:
You have use to slope intercept and formula to get the answer.
Use desmos!!! It’ll help and show you a graph!!
Multiply the first equation by 2 to then use elimination by adding the 2 equations.
So, 14x-2y=14
+. x+2y=6
Equals 15x=20 so x=20/15=4/3
Plug in to first equation to get y
7(4/3)-y=7
28/3-y=7
28/3-y=21/3
So y=7/3
Plug both x and y into second equation to check
4/3+2(7/3)=
4/3+14/3=18/3=6 it works
So x=4/3, y=7/3
Hope this helps! Have a blessed day!
