Suppose you are in the market for a new home and are interested in a new housing community under construction in a different city.
a)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.
b)The sales representative later indicates that there are 3 times as many homes available with the second floor plan than the first. Write an equation that illustrates this situation. Use the same variables you used in part a.
c)Use the equations from part a and b of this exercise as a system of equations. Use substitution to determine how many of each type of floor plan is available. Describe the steps you used to solve the problem.
d)What are the intercepts of the equation from part a of this problem? What are the intercepts from part b of this problem? Where would the lines intersect if you solved the system by graphing?
Can someone please help me? I am weak at word problems at the same time weak at graphing and inequalities, If someone could give me a couple tips or formula how to solve these problems I would appreciate it thank you so much...

would A. be y=x+56?

The same question was posted way back in July and elaborately answered by Marth
