Let the original number be y
Therefore the new number is given by the expression
2y + 6
2x + 7
It is 2n + 20.
2x + 5
(2a - 5). Take the value of a. Double it to get 2a Take away (subtract 5) to get 2a - 5

2x - 2
2x + 7
It is 2n + 20.
2t + 5
2x + 5
x2+7
Double mean to multiply.For example: the algebra expression 2x can be written in the English Phrases like-Double a Number-Twice a number-Two of a number-Two times a number-or the product of two and a number.
Each term is double the previous term and so the next term will be 64
If you mean: kk-5 then it can be k^2-5 But if you mean: k+k-5 then it can be 2k-5
(2a - 5). Take the value of a. Double it to get 2a Take away (subtract 5) to get 2a - 5

Double verticle lines surrounding an expression means to take the absolute value of the expression. The absolute value of an expression is the expression if it is positive, and the negative of the expression if it is negative, i.e. the unsigned distance from zero. Analytically, in order to process the expression, the absolute value of an expression is also the square root of the square of the expression.
