---
y/x = 2/3
x = 6*3 ft
---
put the system of linear equations into standard form:
---
y = (2/3)x
x = 18
---
(2/3)x - y = 0
x = 18
---
0.666666x - y = 0
x = 18
---
copy and paste the above linear system in standard form into this matrix-method solver:

---
solution by matrix method:
x = 18 ft
y = 12 ft
---
area = xy = 18*12
area = xy = 216 sq.ft
---
now by substitution:
---
y = (2/3)x
x = 18
---
y = (2/3)*18
y = 2*6
y = 12
---
solution by substitution method:
x = 18 ft
y = 12 ft
