a. The sales representative informs you that there is a total of 96 houses for sale. Of these 96, some have one floor plan while the others have a different floor plan. Use x to represent floor plan one and y to represent floor plan two. Write an equation that illustrates the situation.

let x= one floor plan and y= two floor plan. so X + Y= 96
ex 37 houses have 1 floor plan. how many have two flow plans?
37+ Y =96. solve for why by subtracting
37 37
Y=59.
to check plug 59 into the first equation 37 + Y= 96 > 37 +59= 96
