To do this problem, you need to make a system of equations and let statements. Let x = the cost of a rose bush. Let y = the cost of a pot of ivy. 6x+3y =39. 2x+3y=27. Now, subtract the two equations to get 4x=12 (6x-2x,3y-3y,39-27) Now, divide both sides by 4 to get x = 3. Plug 3 in for x to solve y. 39-18=21. 21=3y. Y=7. 27-6=21. 21=3y. Y=7. I hope this helped! Sorry if it’s confusing.
