x=-3 or x=5
-4
Then the number is 3
To express "16 more than twice a number" in mathematical terms, you would write it as 2x + 16, where x represents the unknown number. This expression indicates that you first multiply the number by 2 (twice the number) and then add 16 to the result.
7
x=-3 or x=5
(92 x 2) - (9 x 2) = 162 - 18 = 144 The number is therefore 9.
Five more than twice a number is -13 find the number
The square of 9 more than a number is equal to nine more than the square of a number. What is the number?
The area of a square is equal to twice the square's perimeter.
2n + 2 = 2(n + 1)Since you have been given that it is twice a variable with the variable only, you have 2n, and adding 2 yields 2n + 2, or 2(n + 1).

Then the number is 3
Let's call "a number" x. Then 5 more than twice x is 5 + 2x.
One number is eight more than twice another if their difference is 25. The larger number is 42
In otherwords..................... 70 = x + (2x + 4) Solve for x x = 22 Taken from this website - http://www.intmath.com/Basic-algebra/Algebra-problem-solver.php
