Answer:
You can solve the equation 13 + (6 + x) = 20 in two ways:
Explanation:
1. **Algebraic Method:**
- Start by simplifying the equation by adding 13 and 6 to get 19 + x = 20.
- Then, subtract 19 from both sides of the equation to isolate the variable x: x = 20 - 19.
- Finally, simplify to find the value of x: x = 1.
2. **Graphical Method:**
- You can also visualize this equation on a number line or a graph. Plot the point 13, then from there, move to the right by 6 units to reach 19. From there, continue moving to the right by 1 unit to reach 20. The point where you stop is the solution, which is x = 1.
Both methods will give you the solution that x = 1.
