Answer :

Certainly! Let's solve this step-by-step:

1. Define the variable:
Let the number be [tex]\( x \)[/tex].

2. Set up the condition:
According to the problem, the number [tex]\( x \)[/tex] is as much greater than 15 as it is less than 51. This means the distance of the number [tex]\( x \)[/tex] from 15 is equal to the distance of the number [tex]\( x \)[/tex] from 51.

3. Express the distances mathematically:
- Distance from 15 is given by [tex]\( x - 15 \)[/tex].
- Distance from 51 is given by [tex]\( 51 - x \)[/tex].

4. Set up the equation:
Since the distances are equal, we can set up the equation:
[tex]\[ x - 15 = 51 - x \][/tex]

5. Solve for [tex]\( x \)[/tex]:
By combining like terms, we get:
[tex]\[ x + x = 51 + 15 \][/tex]
[tex]\[ 2x = 66 \][/tex]

6. Divide both sides by 2:
[tex]\[ x = \frac{66}{2} \][/tex]

7. Simplify:
[tex]\[ x = 33 \][/tex]

Therefore, the number that is as much greater than 15 as it is less than 51 is [tex]\(\boxed{33}\)[/tex].
