Question 220661: The sales representative here tells you they also have two floor plans available, but they only have 38 homes available. Write an equation that illustrates the situation. Use x and y to denote floor plan #1 and floor plan #2 respectively.
For this part I did, x+y=38 but from here I'm not really sure if I know how to do this.
The representative tells you that floor plan #1 sells for $175,000 and floor plan #2 sells for $200,000. She also mentions that all the available houses combined are worth $7,200,000. Write an equation that illustrates this situation. Use the same variables you used in part a.
Use elimination to determine how many houses with each floor plan are available. Explain how you arrived at your answer.
I started by making this equation: 175,000x + 200,000y = 7,200,000 I think I am on the right track but I am not sure, word problems and Algebra alone confuse me very much.

Question 222888: find all of the ordered pairs, (x,y) of integers that satisfy all four of the given equations: 5*x*3*y=180, x^2+y^2=40, 8*x-8*y=32, 12x/4y=1 The ordered pair has to satisfy all equations and i have to find all of them. for example, if x=5 and y=9, that ordered pair needs to work for every equation. I'm guessing since it says find all of them, there is probably more than one.

Question 223886: okay... :) I am in 8th grade and curently takeing Algebra 1. We are working on solveing Multi-step equations. I am doing good with it but there is just one question on my homework that is truely stumping me. the question is...
5=-9-p/4<<(what i have so far) 5=-9-p/4<< (origanal question)
+9 +9
14=-p/4
i am unsure what to do with the fraction in the problem... the inverse operation would be multiplacation but im not sure how i am supposed to solve this... (oh... i am trying to solve for P)
