Suppose the supply cure ... and Y= x+1 the demand curve y = axta a market equilibrium requires Denang Demand = supply => xt = -x +9 => 2x =8 => x= 4 I Hunce market equilibrium ocims at X=4 and y=x+1 = y = 4+1 = 5 Thes, market Y=5 equilibrium quantity X=4 and Price - supply conuc A -9 B7 400 Demand Doź ☺ . !
