None of the "following" does.

twice the difference of three times a number and eight
None of the "following" does.
2x - 16 = 3x/18
n<7
3x + 5 = 33 - 4 (which is true when x = 8)
204.8, 1638.4, 13107.2 Every number is eight times the previous one.
Call the unknown number n in each instance. (This does not necessarily mean that n will have the same value for each equation.) Then the three equations are: 1. 14 = n + 8. 2. n - 2 = 9. 3. 6 + n/5 = 10.
This forms a linear equation in x. Let the number you are looking for be x.Then,3x - 23 = 343x = 34 + 233x = 57x = 57/3x = 19Therefore, the number you're looking for is 19.
Let's represent the number as (x). The phrase "Eight less than five times a number" can be translated to (5x - 8), and "is seven more than the number" can be translated to (x + 7). Therefore, the algebraic equation representing the given phrase is (5x - 8 = x + 7).
