Need Help! Economics Problem!?

Question

How do I solve this:

Assume the demand for the commodity is represented by the equation P = 10 - 0.20Qd and supply by the equation P = 2 +0.20Qs where Qd and Qd are quantity demanded and quantity supplied, respectively and P is the price. Using the equilibrium condition Qd = Qs, solve the equations to determine equilibrium price and quantity.

Need your help on this! Thanks!!

Answer 1

10-0.2Q=2+0.2Q

0.4Q=8

Q=20

P=10-0.2*20=10-4=6

Equilibrium: Q=20; P=6
