In this question, the equation of demand curve is given by qd plus 4p minus 24 equals to 0.
00:14
So, this implies 4p equals to 24 minus qd and from here p equals to 24 minus qd divided by 4.
00:28
Now, this is the equation number 1 and next supply curve equation, supply curve equation is given by 13p minus qs equals to 27.
00:44
So, this implies 13p equals to 27 plus qs.
00:54
So, this implies p equals to 27 plus qs divided by 13.
01:03
This is equation number 2.
01:05
Now, from equation, from equation 1 and equation number 2, 24 minus qd divided by 4 equals to 27 plus qs divided by 13.
01:25
But, but at equilibrium, at equilibrium demand and supply, demand and supply both are equal.
01:41
So, at equilibrium demand is equals to supply.
01:45
So, this implies qd equals to qs equals to q.
01:51
So, from here 24 minus q divided by 4 equals to 27 plus q divided by 13...
