How do I solve by putting Qd = Qs?

**Equilibrium Price and Quantity Analysis**

1. **Equilibrium Price and Quantity**

   Determine the equilibrium price and quantity based on the demand and supply equations:
   
   - Solve by setting Qd = Qs.
   
   \[
   Qd = 10 - P
   \]
   
   \[
   Qs = P
   \]

   Quantity is from 0 to 10 units on the x-axis.
   
   Price ranges from $0.00 to $10.00 on the y-axis.
   
   Plot the Supply and Demand curves accordingly.

2. **Plotting Demand and Supply Curves**

   Use the following schedules to draw the Demand and Supply curves:

   - **Demand Schedule:**  
     \[
     \begin{array}{c|c}
     Q & P \\
     \hline
     0 & 10 \\
     1 & 9 \\
     2 & 8 \\
     3 & 7 \\
     4 & 6 \\
     5 & 5 \\
     \end{array}
     \]

   - **Supply Schedule:**  
     \[
     \begin{array}{c|c}
     Q & P \\
     \hline
     0 & 0 \\
     1 & 1 \\
     2 & 2 \\
     3 & 3 \\
     4 & 4 \\
     5 & 5 \\
     \end{array}
     \]

3. **Graphing the Demand Curve**

   From step 2, draw a graph and identify the equilibrium point (Point A). Illustrate how the demand curve shifts when consumers’ income decreases.

4. **Graphing the Supply Curve**

   Using step 2, draw another graph and mark equilibrium Point A. Show the effect on the supply curve when more producers enter the market.
