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.

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.
we will use the variable 's' to represent your savings: 2s+10
