Suppose you are in the market for a new home and are interested in a new housing community under construction in a different city.
The sales representative informs you that there are two floor plans still available, and that there are a total of 56 houses available. Use x to represent floor plan #1 and y to represent floor plan #2. Write an equation that illustrates the situation.
x + y = 56
The question was probably worded in a confusing way for you. They really meant that x is the NUMBER OF HOUSES AVAILABLE with floor plan #1 etc, and y is the number available with plan #2.
That should make the equation rather obvious.
