Since the second equation gives a value for a, we can substitute it into the other equation to find a value for B.
Let's substitute b-2 into the first equation wherever there is an a.
a - 3b = 4
(b-2) - 3b = 4
b - 2 - 3b = 4
-2 - 2b = 4
-2b = 6
b = -3
Now let's find a by substituting -3 into either of the equations to find the value of a.
a = b - 2
a = -3 - 2
a = -5
So your solution set is (-5, -3)
Answer: There are 180 ways of different furniture combination that are possible.
Step-by-step explanation:
Since we have given that
Number of couches = 4
Number of coffee tables = 5
Number of recliners = 9
According to question, Bruce and Krista are going to buy a new furniture set for their living room. They want to buy a couch, a coffee table, and a recliner.
So, Number of ways of choosing a couch from the number of couches will be
Number of ways of choosing a coffee table from the number of coffee tables will be
Number of ways of choosing a recliners from the number of recliners will be
So, the number of different furniture combinations are possible is given by
Hence, there are 180 ways of different furniture combination that are possible.
