To find the other number, we start with the equation describing the relationship given in the question. If we let that unknown number be represented by ‘y’, the relationship can be written as:
- x – y = 6
From this equation, we can express ‘y’ in terms of ‘x’:
- y = x – 6
This means that to find the value of ‘y’, we simply need to subtract 6 from the value of ‘x’. So, if you know the value of ‘x’, you can easily determine what the other number is. For example, if ‘x’ is 10, then:
- y = 10 – 6 = 4
In conclusion, the other number is always found by subtracting 6 from the value of ‘x’.
