Let the number be x:- If: 7x -22 = 125 Then: x = 21

141+20=161, 161/7=23. The answer is 23. It is algebra

81.

If the number, x, has 10 subtracted from twice it to make 28, then x must be 19. 2x - 10 = 28 2x = 38 x = 19

7x - 25 = 15 7x = 40 x = 40/7 or 5 and 5/7

*A+ answer is 4 .:Sandy:.

7N - 4N = 24

25-5x=85 -25 -25 -5x=60 60/-5=-12 x=-12

Let the number be x:- x-(25*4) = 63 x-100 = 63 x = 63+100 x = 163

21

The answer is 23 itself 23 + 23 + 23 = 69 = 23 x 3 then 69 - 23 = 46

The number is 5.

3x - 20 = 46 3x = 46 + 20 3x = 66 x = 66/3 x = 22 Therefore, the number is 22! :)

It is the number that is added, subtracted, times, or divide in a pattern to (n) or the start number.

24 - n = 5n n = 4

There are an unlimited number of times that any word appears in the world. Certain words appear a certain number of times in a certain piece of literature.

There is nothing in the description you have given which tells us the amount of that unspecified number, therefore, the answer could be anything. If you want to solve for an unknown number you need an equation. You might have said four times a number added to -9 subtracted from triple the sum of nine times the number and eight is equal to zero. Then we can solve the equation.

7x - 4x = 27 3x = 27 x = 27/3 x = 9 Therefore, the number is 9. :)

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!

18. 3 x 18 = 54 54 - 5 =49

The number is 8.... 7 x 8 = 56.... 2 x 8 = 16... 56 - 16 = 40
