Answer:

Step-by-step explanation:
Represent the sofa with S and the love seat with L.
So, we have:
--- Total Cost

Required
Determine the value of L
Substitute 2L for S in the first equation.


Divide both sides by 3



<em>Hence, a love seat costs 117.0</em>
<em></em>
<u>Using Graph</u>
See attachment for graph
S is plotted on the y-axis and L is on the x-axis.
The green line represents
while the orange line represents 
When the line of the graph is traced to the x-axis, we have:

To find the midpoint you divide the sum of the x and y coordinate by 2 because you want to find the middle.
((2+4)/2,(1+-3)/2)
So simplify and get answer
(3,-1)
