Important Points to Solve the Problem Suppose number is “y”. 7y – 15 (when 15 is subtracted from 7 times the number). 2y + 10 (result is 10 more than twice the number). So, 7y – 15 = 2y + 10 Through this equation we can easily figure out the value of “y” (y = 5 answer). To Find Number = ? Solution Find a Number Such That When 15 is Subtracted From 7 Times the Number, the Result is 10 More Than Twice the Number | Solution | Problem Solved | CSS Examinations Let suppose Required number = y According to the given condition; 7y – 15 = 2y + 10 7y – 2y = 25 5y = 25 y = 5 answer Conclusion Find a number such that when 15 is subtracted from 7 times the number, the result is 10 more than twice the number. The number is 5.

If we call the number that we're looking for "x", then we can translate the question like this: When 15 is subtracted from 7x, the result equals 2x + 10 Or: 7x - 15 = 2x + 10 Then it's a simple matter of simplifying the equation. Group like terms on either side of the equal operator: 7x - 2x = 10 + 15 Then add them together: 5x = 25 And factor five out of both sides: x = 5 Giving you the answer. How man times must the number m be subtracted from m squared to give a restlt of zero? Answer: 'm' times. Examples: If m=2, Then m2 = (2x2) = 4 -> 4-2-2 = 0 (So subtracted TWICE) If m=4 Then m2 = (4x4) = 16 -> 16-4-4-4-4 = 0 (So subtracted FOUR TIMES) This works no matter how large the number is!
