---
x = y + 180
2x + 2y = 1060
---
put the system of linear equations into standard form
---
x - y = 180
2x + 2y = 1060
---
copy and paste the above standard form linear equations in to this (matrix method) solver:

answer1:
x= length = 355 ft
y= width = 175 ft
---
---
now by substitution:
---
2x + 2y = 1060
2(y + 180) + 2y = 1060
2y + 360 + 2y = 1060
4y = 700
y = 175
x = 355
---
answer2:
x= length = 355 ft
y= width = 175 ft
---
NOTE: the results from matrix method agrees with result from substitution

The length of a football field is 180 feet more than its width. if the perimeter of the field is 1,060 feet ,find the length of the field.
----------------
Perimeter = 2(length + width)
--------
1060 = 2((w+180)+w)
-----
530 = 2w+180
-----
2w = 350
-----
width = 175 feet
length = w+180 = 175+180 = 355 feet

The length of a football field is 180 feet more than its width. If the perimeter of the field is 1060 feet, find the length of the field.
X = length
Y = width
x = y + 180
2x + 2y = 1060
x – y = 180
2x + 2y = 1060
2(y + 180) + 2y = 1060
2y + 360 + 2y = 1060
4y + 360 – 360 = 1060 – 360
4y = 700
Y = 175
x = y + 180
x = 175 + 180
x = 355
