Write the equation that satisfies the parameters: three times the difference of a number and 10 equals the sum of 25 and that same number. (1 point) 3x + 10 = 25 - x; 3x - 10 = 25 + x; 3(x + 10) = 25 - x; 3(x - 10) = 25 + x

1 answer

The problem states that three times the difference of a number and 10 equals the sum of 25 and that same number. Let's denote the unknown number as x.

  1. The difference of the number and 10 can be written as x10.
  2. Three times this difference is 3(x10).
  3. The sum of 25 and that same number is 25+x.

Putting it all together, we set up the equation:

3(x10)=25+x

So, the correct equation is:

3(x10)=25+x
