# Find The Equilibrium Price And Quantity For (a) Qd=35-p And Qs=-7+0.5p (b) Qd=30-2p And Qs=-712+1.5p

Qd= 30-2p
qs= -712+1.5p

qd=qs
Thus,   30-2p   =    -712+1.5
30+7.12   =     1.5p+2p
742   =   3.5p
742/3.5     =   p
212   =    p

Sub the Value of P in equation 1 to determine equibrium demand
qd= 30-2p
qd=30-2(212)
qd=30-424
qd= -394

Thus the equilbrium price is 212
and the equilbrium quantity demanded is -394 units

qd=35-p and qs=-7+0.5p
Qd=Qs
So 35+7=.5p+p
42=1.5P
P=42/1.5
=28
Put valueof P in any above equation to get Eqbm. Q.
Eqbm. Q =-7+.5(28)
Eqbm. Q = 7
Interptation:At eqbm.P=27 we can take 7 units of Q.

qd=30-2p and qs=-712+1.5p
Qd=Qs
So we can write as
-3.5P = -742
3.5P = 742
P=742/3.5=212
Eqbm. P = 212
Put valueof P in any above equation to get Eqbm. Q.
Eqbm. Q =30-2(212)
Eqbm. Q = -394
Interptation:At eqbm.P=212 we can take -394 units of Q.

Qd= 30-2p
qs= -712+1.5p

qd=qs
Thus,   30-2p   =    -712+1.5
30+7.12   =     1.5p+2p
742   =   3.5p
742/3.5     =   p
212   =    p

Sub the Value of P in equation 1 to determine equibrium demand
qd= 30-2p
qd=30-2(212)
qd=30-424
qd= -394

Thus the equilbrium price is 212
and the equilbrium quantity demanded is -394 units
