To write the equation based on the parameters provided, let's break down the statement:
- "three times the difference of a number and 10" can be expressed as \(3(x - 10)\).
- "equals the sum of 25 and that same number" can be expressed as \(25 + x\).
Putting this together, we get the equation:
\[ 3(x - 10) = 25 + x \]
This matches the option:
3(x−10)=25+x
So the correct response is \(3(x−10)=25+x\).
