Given:
A number whose double exceeds its half by 9
To Find:
The number
Solution:
Step 1:
Assume that number is x
Step 2:
Find Double of the number
2x
Step 3:
Find half of the number
x/2
Step 4:
double exceeds half by 9 hence
2x = x/2 + 9
Step 5:
Solve for x
4x = x + 18
=> 3x = 18
=> x = 6
Hence number is 6 whose double exceeds its half by 9
