You can put this solution on YOUR website!
First, assign variables and form the equations.

x square feet of grass
y numbers of geraniums

system%284x%2B3y=18%2C2x%2B6y=18%29, and you can study those to figure how they were formed.

Do you still need help with what to do with the system of equations once it is created?
