Question 828679
---
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 linear system in standard form into this matrix-method solver:

---
solution by matrix method:
x = length = 355 ft
y = width = 175 ft
---
now by substitution method:
---
x = y + 180
2x + 2y = 1060
2(y + 180) + 2y = 1060
2y + 360 + 2y = 1060
y = (1060 - 360)/4
y = 175
---
x = 175 + 180
x = 355
---
solution by substitution method:
x = length = 355 ft
y = width = 175 ft
