Let's call "a number" x. Then 5 more than twice x is 5 + 2x.
n = number.2n + 6=====
The algebraic expression for three more than a number is: X + 3
2x+3 where x is the unknown number
Five more than twice a number is -13 find the number
2x + 5
If you want "the number" write 5 + 2X = 7 2X = 2 X = 1. So "five more than twice of one is 7.

Let's name the first number "X" and the other number "Y" thus: 2X+5Y is the same thing as twice a number more than five times another
2x+5
If the number is 'z', then five less than twice the number is ( 2z - 5 ).
It is 5n - 8 <= 2n + 10
If the unknown number is q then: 2q+25 = 72
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.
3*(n - 5) = 2*n + 11
x = 11
