I am trying to complete a checkpoint for class and need a couple clues for the world problems. I always have a problem with word problems. It's about buying houses;

a. sales rep. states there 56 houses for sale with two floor plans available. x is floor plan one, y is floor plan two. what equation illustrates this?

Is it x + y = 56 ?

b. sales rep. states there are three times as many homes available with floor plan two versus floor plan one. what equation illustrates this?

Is is x = 3y - 56 ?

Use substitution to determine how many of each floor plan is available.
