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!

Answer:
w(2w+4)
Step-by-step explanation:
we know A = l * w
and Perimeter = 2l + 2w
we want to find l in terms of w
2l + 2w = 6w + 8
2l = 4w + 8
l = 2w + 4
so A = w * (2w + 4)
