If the number is represented by variable x, then twice the number is represented by 2x.
2N-13
It is an algebraic expression in the form of 2x+6 whereas x is the unknown variable

If the number is represented by variable x, then twice the number is represented by 2x.
x + 2x
2N-13
It is an algebraic expression in the form of 2x+6 whereas x is the unknown variable
-7754
The number is -6.
Watch closely ==> [ 1 - 2x ] .
In this case, you'll have to use a variable. Variables are basically a symbol which stands for a number. Let's use the variable "m". You're searching for 58 less than a number. That is basically just "word form" for a number, or a variable, minus 58. So if we use the variable "m", the expression will be m-58. Remember that you can use any variable you want.
3.45
we will use the variable 's' to represent your savings: 2s+10
12-8 = 4 and 2*4 = 8
If the number is n then twice the number is 2n and 7 less than twice the number is 2n - 7This could also be a boolean variable based on another variable. If the number is less than or equal to 3.5, the variable is false. Otherwise, it is true.
