2(n - 11)
twice the difference of three times a number and eight
2x-16
It is 3*n - 5
L = S + 11; 2S + 3(S + 11) = 123, ie 2S + 3S + 33 = 123ie 5S = 90 ie S = 18 and L = 29
47 Impossible problem!
If you mean the difference between -11 and 2*(-11), then it's 11.

twice the difference of three times a number and eight
The difference between five times a number and twice that number can be expressed mathematically. If we let the number be represented by ( x ), then five times the number is ( 5x ) and twice that number is ( 2x ). The difference is calculated as ( 5x - 2x ), which simplifies to ( 3x ). Thus, the difference is three times the original number.
The difference between a number x and twice y is equal to fifteen.
It does not mean anything at all. "Twice a number" is only one number while "the difference" must refer to two numbers, not just one.

One number is eight more than twice another if their difference is 25. The larger number is 42
Twice the number is something like 3x2, 4x2.... Squared is 3x3, 4x4. It's one number multiplied by itself twice
