n - 4
To write "4 is less than," you would use the symbol "<" to represent "is less than." Therefore, it can be expressed as "4 <" followed by the number you are comparing it to. For example, if you want to say that 4 is less than 5, you would write "4 < 5."
You would write it as x/3 -4, where x is whatever the number is.
n - 4 = 19
5x-4
4x - 500
4
Let the number be x and so the expression is: 4x -7
4p - 9 > 15
2x = <4
3x - 4 = 8
x - 4
