If price is increased to N3, how much is the excess supply?

Qd=20-4P, Q=6P+12, P=#3.....i.e, Substitute P=#3 into eqn1&2... Qd=20-4(3)=20-12=8... Q=6(3)+12=18+12=30... Therefore, 30-8=22... So 22 is the excess supply.

Input 3 into Q d = 20 - 4P. You'll get 8 units. Then input 3 into Q = 6P + 12, You'll get 30. Now subtract 30 from 8 and get 22. (:

just simple as ABC.20-4p will give u 16 remeber it has both side then the second is Qs=6p=12 all u have to do here is to minus 20-4 it give u 16 them Qs=6p use the 6p to do to remove the already 16 u will have 10 then add it to 12 it will 12+10 22

20-4p=0
P will be=3
20-4(3)=0
20-12=8
6p+12=0
6(3)+12=0
18+12=30
So 30-8=22✓
