$x - 6$ $x-6$

Explanation:

substitute numbers in, write down EXACTLY what you do and then replace numbers with letters

What is 6 less than 20?

20-6=14 because less than means subtract

Now replace 20 with the letter $x$ $x$

$x - 6$ $x-6$ we do not have an answer as we do not have a value for $x$ $x$

a number $d..d \to x - 6$ $color(white)("d..d")->x-6$
