 ### [Step 2](): Configure Excel Solver
 
+<br>
+
 1. **Go to**: Data > Solver
+
 2. **Set Objective**:  
    - Set **K2** (total cost) to **Minimize**.
+
 3. **By Changing Variable Cells**:  
    - Select **G2:I4**.
+
 4. **Add Constraints**:
    - **J2:J4 = 1** (each task assigned once)
    - **G5:I5 = 1** (each machine assigned once)
    - **G2:I4 = binary** (only 0 or 1 allowed)
+
 5. **Choose Solving Method**:  
    - Use "Simplex LP" or "GRG Nonlinear" (either works for this size).
+
 6. **Click Solve**.
