You can put this solution on YOUR website!
x = area of state A
y = area of state B
---
x = 7y
x + y = 8000000
---
put the system of linear equations into standard form
---
x - 7y = 0
x + y = 8000000
---
copy and paste the above standard form linear equations in to this solver:

solution:
x = area of state A = 7000000 sq.mi.
y = area of state B = 1000000 sq.mi.
