Answer:
Let the required number be ' x '
According to the given problem
- Equation :--- 2(x + 5) = 20
Now, by solving for x, we get
[tex]2(x + 5) = 20 \\ (x + 5) = \frac{20}{2} \\ (x + 5) = 10 \\ x = 10 - 5 \\ \boxed{ x = 5}[/tex]
- 2(x + 5) = 20 is the required equation
- x = 5 is the required value of x
