Whichever has the biggest Denominator if it has the same numerator
1) 2x+1x= 63
2) 3x= 63
3) 3x/3= 63/3
4) x= 21
5) 2(21)+1(21)=63
6) 42+21= 63
The 2 groups would be 42 to 21.

Answer:
a) Demand equation :
b) Supply equation : 
C) The equilibrium quantity and the equilibrium price are 2500 and $ 525 respectively
Step-by-step explanation:
We are given that For each decrease in unit price of $20 below $485, the quantity demanded increases by 250 units.
Since decrease in unit price of $20 increase demand by 250 units
So, Slope =
We are given that The quantity demanded x of a certain brand of DVD player is 3000/week when the unit price p is $485.
Now for demand equation:
Use point slope form : 
So, 
a)So, Demand equation : 
Now to find supply equation
We have two points (0,350) and (2500,525)

b) So, Supply equation : 
Now to find equilibrium quantity and price equate demand and supply equation

So, equilibrium quantity = 2500
To find equilibrium price substitute equilibrium quantity in any equation

C) The equilibrium quantity and the equilibrium price are 2500 and $ 525 respectively
