Question 805645: The perimeter of a rectangle is 22ft the length is 3ft longer than the width. I need to know how to write a system of linear equation and then solve the resulting system.
X will be the length and y will be the width.
I know P=2L+2W
the perimeter is already given which is 22

The perimeter of a rectangle is 22ft the length is 3ft longer than the width.
-----------------
L = W +3
----
2(L+W) = 22
-------------------
Modify for elimination:
L - W = 3
L + W = 11
-------
Add and solve for "L";
2L = 14
L = 7
-----
Solve for "W"
L + W = 11
7 + W = 11
W = 4
