S=a+bP
D=c-dP
S=D
1. Define the solution (the equilibrium price) as p. (Note that I switched to lower case because I want to distinguish between an arbitrary price P and the equilibrium price p.
Define the values for following parameters:
a=1
b=2
c=10
2. Type p (in math mode) and use the command "simplify" to obtain an expression for p that is now a function of the parameter d. Show this expression.
