The solution for finding the width of the wall of the barn is as follows:
W + 4 equals length.
<span>Multiply width time length to equal 160. </span>
<span>W(w+4) = 160</span>
<span>w(squared) + 4w equals 160. </span>
<span>W = 10.80 ft</span>
<span>Therefore, the width of the wall of the barn is 10.80 ft

I hope that helps you.
Answer:
<h2>x = -8</h2><h2>y = 10</h2>
Step-by-step explanation:
Theoretically speaking, both equations need to equal 0.
Let's start with (x + 8)
x + 8 = 0
x = 0 - 8
x = -8
Then, let's go to (y - 10)
y - 10 = 0
y = 10 = 0
y = 10
So, x = -8 & y = 10
Hope that helps!
