You can solve this system of the equations with graphical method or algebra method.
I solve this system with Gaus algorithm
first we divide second equation with number 3 and get x+10y=12
Than subtract first equation from second and get 5y=6 => y=6/5
now we replace y in the first equation and get x+5*(6/5)=6 =>x+6=6
=> x=0 (x,y)=(0,6/5)
Conclusion is that we have one intersection point between this two graphs.
Good luck!!!

Answer:
It is (D)
number of seeds planted per square foot
ED2021
The area of the room = (40 x 24) - (20 x 12)
Area = 960 - 240 = 720 square feet
Divide square feet by width of a strip:
720 / 12 = 60 linear feet.
The answer is D.
