2 more than twice a number. Well, the formula for that would be ( N x 2) + 2. The N stands for number. So, I hope that helps you a little. If you have a number to fill in you would put it in the n spot,
2n + 2 = -10
2w + 2
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).

Twice the difference between a number and thirteen can be written as 2 (b - 13) Five more than twice the difference between a number and thirteen can be written as 2 (b - 13) + 5. The algebraic expression is 2 (b - 13) + 5.
If you want "the number" write 5 + 2X = 7 2X = 2 X = 1. So "five more than twice of one is 7.
2w + 2
(92 x 2) - (9 x 2) = 162 - 18 = 144 The number is therefore 9.
Two is a number. Twice is an operator which means multiply by 2. Several is a non-specific number, more than 2 but not very many.
